I saw the new Hatchet Overland rooftop camper at Overland Expo a few weeks ago and I was mightily impressed. See
https://www.hatchetoverland.com/. It's inspired by the Ursa Minor J30 but has several innovations that I would love to discuss in detail on this forum. Unlike the J30 it opens forward creating a space inside the trunk area that is permanently open for entering/exiting the camper. It allows for a thicker mattress up to 6" - I tried it with a 4" blowup mattress that was very comfortable. There is space on the top to mount maxtrax and solar. It uses your original hard top through modification which saves some money on the Ursa minor options for a working windshield wiper and defroster on the rear window or the sliding windows. My concerns are mostly about weather. It's not clear that it's going to be really weatherproof or even if it will repel moisture and retain heat. The interior led lights didn't look as polished to me but the platform itself seems like it has a lot of potential. I'm not sure if they will accept awnings or how durable they will be. They are a little cheaper than the J30 at 8k installed and the founders are planning a production run this winter. What do those of you with J30 experience think?
Ursa Minor Owner #204 - My thoughts and some answers to questions in this thread. The Ursa Minor Camper weights 125 lbs over the stock hardtop. I Paid $8600 out the door back in 2017. I sold my stock Jeep white hardtop for $1700. I am not seeing a huge price difference even with the new pricing structure. Currently my top would cost $10,000 priced out on the Ursa Minor website. You can then offset the sale of your current hardtop. Something that is not possible with the new Hatchet model.
Bedding - The current Ursa Minor has a 2" foam mattress. I have seen folks add memory foam to the current mattress. Obviously this is not a good combination in cold weather. One thing I have noticed over the years is if you are camping in subzero conditions you can feel the cold coming up from inside the cab of the Jeep while sleeping. This year I have added a 1/4" close cell foam to my mattress cushions. In the past I have also simple inflated a small air mattress over the stock mattress on really cold nights. I leave two full size pillows up top during travel and could probably leave a sleeping bag up there as well but I choose to pull it out do to the expense of the bag.
Overall height - My Jeep has an AEV 3.5RS lift with BF Goodrich KO2 - 315/70r17. I manage to slip into an 7' garage.
Ursa Minor side entrance is fantastic. Chris Shontz has been showing off the benefits of being able to slide into the rear seat, remove your shoes on the rubber floor mat and then simple step up into the camper if equipped with Goose Gear. This simplicity is what makes this setup work. With the Hatchet model how do you open the rear tailgate from inside? If you have to come in through the side door do you crawl back to the standing area? On Dan Grec's Ursa Minor he has removed the rear factory roll bar so he can enter the rear side door and immediately stand up inside the camper.
The Ursa Minor hatches are a pain. There is no doubt about it. JL owners have the new redesign which helps with the stability of the hatch when installed. The JK version has a single spot that when pressed on will cause you to fall through, Doh. Having a micro camper means having trade offs. The huge bonus of having the center hatches is This - When camped you almost always park into the wind. You pop the top and climb up inside. Opening the windows provides a great view with wind protection. Now grab the rear cushion and move it to the front of the bed. You now have a standing table that is approximately 2'x4'. If you opted to add outlets in the corner you can power up your devices while making a quick sandwich. Bonus points for those that take the time to hang a hammock between the roll bar for a seat. One other small caveat if you have a JL. The two rear side indents on the top that most use for an awning are spaced for a collapsible ladder. If sleeping two full-size adults access through the side fabric of the camper might be a great option. I believe the ladder could easily be stored on the bed during transit. I would want to make a heavy canvas bag to protect the bed if stored this way. The two inside indents on both sides are the balance point for removing the top(just FYI).
Noise - The added thickness of the top is significantly quieter than a stock top. I have a completely LineXed top and I can not feel any heat transfer inside the cab. The LineX is scorching hot to the touch on sunny days. I will take that trade off for the durability and use the top like a truck bed. I simple strap Maxtax to the roof with straps and have added a very low profile Merlin Solar Panel as well.
