JK J30 FAQ

How tall is a Jeep with a J30 or J180 installed? Can I get it into my garage or a parking structure?

The Jeep Wrangler with OEM Hard Top is 71” tall (1.8 m or 5’-11”.) Mounting a J30 will increase the height by 10" depending on options selected: A stock Jeep with either a J30 or J180 camper mounted will be 81” tall (6’-9”.) With racks (J30 Only) Thule & Yakima racks (bars/towers) are easily removed when not in use, but the mounts remain in place and are about 1” high, increasing total height of the camper to 82” (6’-10”.) With Thule or Yakima rack towers and bars in place, the camper will be from 82" to 86” (6’-9”) tall depending on specific rack. As there are a large number of attachments offered by Thule & Yakima, the best resource for total height of rack + attachments is the Thule or Yakima website. For a rough idea, Kayak Saddles or rollers add another 3"-6” Bike Trays add 3”-6” Kayak "J-Bars " add 24” Ski Racks add 6” to 12” Many modern suburban garages are 7’-6” or more, leaving sufficient room for a Jeep with camper, but you may need to remove the racks depending on your choice of accessories. Total height can vary based on loading (passengers and gear) in addition to any changes dues to suspension or tire changes. Measure garage and Jeep before pulling in full speed!

How much weight can be put on the racks? Can the camper be opened with gear (bike,kayak,etc) on the racks?

Note that we are unable to mount racks on the J180 (Habitat) due to the impact on the torsion spring and possible interference when opening. For the J30 with optional rack mounts and rack: With the camper closed, you may carry gear on the racks subject to the load ratings specified by the rack manufacturer. Both Thule and Yakima rate their racks at 75 lbs per bar, but that rating should be taken with caution. Loading at capacity on a washboard road will likely result in issues or failures of the rack (not the camper) The more gear strapped to the racks, the more effort is needed to open the camper. We advise no more than 30lbs on the racks in order to easily raise the roof. This limitation is fairly generous in the pop-top industry. With 30 lbs or more on the racks, the opening of the camper will require increasingly more muscle power. Closing the camper will also require coordinating with a colleague to get the canvas tucked in neatly. In a practical sense, opening/closing with 2 bikes or 1 sea kayak is manageable, but 2 sea kayaks is really a struggle. Adding weight high on any vehicle impacts the center of gravity, and stability. We recommend carrying only things that won't fit in the camper on top - such as kayaks, surfboards, or bikes. Heavy items such as tires, tools and liquids (water or fuel) should be carried inside or as low as possible on the vehicle

Adventure Trailers/AT Overland (AT) sold a Jeep camper top called the JK Habitat that is very similar to the Ursa Minor product. How is the Ursa Minor J180 different from their camper?

Ursa Minor designs and manufactures composite campers, including the ECamper, the J30 and the J180 products. Our expertise is in engineering, design and production of vehicle based campers. We do conversions and installations of our products in San Diego, CA and ship worldwide to dealers and retail customers. AT Overland was an Ursa Minor dealer from 2011 to 2015. The JK Habitat was AT's name for the Ursa Minor J180. AT Overland now sells a completelyy diffferent camper called a JK Habitat. This camper is not made by Ursa Minor, and does not allow access from inside the vehicle. It is a permanentl mounted roof top tent for Truck Beds not an integrated camper, though the tent is similar.

What models or years do your campers fit?

The J30 and J180 fit:

  • Jeep Wrangler Unlimited (JK Series) 2007 through 2018. We also offer a version for the JL series
  • Any trim version, X, Sport, Sahara, Rubicon and any other special edition trim levels (Anniversary, Altitude, etc)
  • Soft top or hard top versions
  • Right or left hand drive versions
  • Any engine (Gas/Diesel)
  • Any transmission (Manual/Automatic)
  • J8 Four-Door - Military Specification Wrangler

The J30 and J180 will NOT fit:

  • 2004-2006 Wrangler Unlimited (LJ series)
  • 2 Door Jeep Wranglers 2 Door
  • J8 long bed Military Spec Wrangler

Is there an Ursa Minor top that fits a 2 door?

We do not have a camper top that will fit a 2 door Jeep.

We evaluated the potential to design a camper top for a 2 door jeep, and do not at this time expect it to be feasible.

  • The LJ had a very limited production
  • The JK 2 Door is just short enough that we don't have a good way of adding standing room or an access way, and the bed would be quite short.

If you have a 2 door, the best choice for vehicle based camping is a external rack with a roof top tent.

Do I need a Jeep with a hard top or soft top to install one of your campers?

Installing a J30 or J180 does not require utilizing any parts or components from the OEM Hard or Soft tops. If you are buying a new Jeep, the base Jeep will come with a soft top. You can upgrade to a hard top at purchase for $995, but a new one from Jeep is about $2500 plus shipping. This difference in price means an OEM top could be sold for $1500 - $1750, which nets $500 - $750 to apply to an Ursa Minor top. Soft tops are a bit harder to sell, but you still might get $300 - $500 for a brand new one. Check ebay, or your local craigslist to see what prices are for used tops in your area. Where can I see one of your campers? The easiest place to see a camper is our facility in Chula Vista, CA where we build and install them. For those outside Southern California, that can be challenging. Alternate opportunities are: Trade shows and events UMV will attend, as posted on the home page Visiting a UMV retailer/installer, list being added soon Contact UMV via email, including your phone number, city and state and we will refer you to any local owners

Can I install or remove the camper easily?

It's straightforward to remove the camper, but calling it easy relies on having the team, skills and equipment needed on hand. While the steps are similar to removing an OEM hard top, the weight and awkward size of the camper tops makes installing or removal a task that involves preparation. The J180 is much heavier than the OEM top. It is typically installed with a forklift or hoist by trained installation shops, and is intended to remain on the vehicle for the long term. It can be removed for servicing, customizing or for transfer to another Jeep, preferrably by the shop that installed it originally. The J30 is heavier than the OEM top, but can be removed/installed by hand with 3 or more people. The challenge is not the weight, which is about 250 pounds, but balancing and lifting it over the roll cage and past the rear tire carrier. If the Jeep suspension is lifted, or if larger tires are mounted, the ergonomics become difficult and we would recommend using a hoist.

The campers all have gray canvas, can I special order an alternate color tent?

We elected to go with gray as a neutral color that hides the dirt & grime that seems to accompany outdoor adventures.

We can custom sew a tent from an alternate Sunbrella color with these constraints:

  • The color must be available in the 60" roll size (sorry, no floral prints)
  • Order to ship time may increase while we wait for the one-off tent to be sewn
  • The camper will be considered a custom build with progress payments needed during build
  • There is no guarantee that a Sunbrella color will match a vehicle body color in any way, even if it looks like it does on the computer
  • Exact price for a custom color will be quoted on request

How much room is there on top? How big is the bed?

You'd be surprised how much room we squeezed out of the Jeep. For the J30 JK pop-up: The sleeping area is 7 feet long and is 4 feet wide at the widest point. Due to the sloping roof, the height of the sleeping area changes over the length of the car. At the front of the car where your feet go, the height is 12". At the back of the car where your head goes, the height is 42". With the top raised, standing room in the access way is about 6’6”.

Will I collapse the roof when I climb up into the bed?

No

Is it possible for Ursa Minor to customize either the J30 or J180 with a sink, toilet, shower or table?

The Jeep as a camper base is fantastic for off road adventures, but it is not a van. The camper has an access way to enable entry/exit from the bed and to provide standing room, but the size of this access way is limited by the OEM roll cage. We do not modify the roll cage as part of the conversion. With limited space inside, one approach to add cooking capabilities is similar to a tear-drop trailer. A stove, refrigerator,storage drawers and table are added at the rear to create a galley, and used while standing at the open tail gate. While this is a fair-weather kitchen, it is also recommended that in bear country you cook some distance from the camper to avoid having an ursa major check out your Ursa Minor! Installation of a rear galley can be quoted, sourced and installed on request.

How long does it take to make one of these Jeep hard tops?

As one can imagine, the lead times vary based on the season, longer in spring, shorter mid-winter.

Current lead times are 30 to 60 days.

In other words, we'll be able to install or ship your top about  1 month from the date the deposit is made. Certain options, such as paint to match, or custom work will increase lead time.

Once your installation appointment date arrives, we will need your car on-site for a full day to install a J30. If there is additional custom work being done, we will plan this out prior to installation.

If the Jeep has additional accessories that must be removed or that we will need to work around, there may be more time required.

How durable/waterproof is the tent?

The J30 tent fabric is a highly durable and water resistant marine canvas called Sunbrella®. Much thicker than traditional tent fabric, it's mold and mildew resistant and does not shrink. You may find much more information specific to Sunbrella® on the manufacturer's website Will the conversion change how the inside of the Jeep ceiling looks? Yes, the interior of the J30/J180 is fully lined with black carpet. The area above the driver/navigator seats can also be customized with our Navigator map pockets and storage.

Can I drive with the top up?

No. Though you can move the Jeep around in a camping spot if it's less than 50 feet of distance or so.

What sort of MPG can I expect from a Jeep Wrangler Unlimited with a camper installed?

Due to changes in the engine over the course of production, the mpg rating for the Jeep differs depending on year. We can say that the addition of a J30 camper will not impact your mileage significantly, if at all. Adding racks will cause a 1 - 2 mpg loss, and we recommend removing the cross bars if you will not be carrying a load for best mileage.

I live a long way from San Diego. Can you ship a JK J30 camper to me?

Yes, we can ship domestically or worldwide. There are two cost elements to shipping:

  • Crating
  • Transport

Crating up a camper involves more than a box and foam peanuts!  The crate has to meet freight regulations,but you will have enough wood to build a workbench, tree-house or have a nice bonfire (after removing top!)

Transport cost from San Diego (All prices are ex-works, or FOB, Chula Vista 91911) across the US varies widely, especially as the price of fuel goes up or down.  It also matters if the destination is a major city on the interstate or a small town off the grid. 

The destination must be able to handle the load, which requires either a fork lift or a loading dock.  The camper can not be shipped to a residential address, but we can ship to businesses or a freight depot.

International Shipping

For international shipments, crating costs increase due to the need to use heat-treated lumber for the crate to meet regulations. Crates typically go by sea, but we have air shipped campers.

The other consideration for any international shipments is that we can only ship to the Port of Entry, not to a final address.  Customers must arrange in-country transport, as well as payment of duties/tariffs.
