Ursa Minor J30 Pop Up Camper

From the very beginning I didn’t want a roof rack on my Jeep. If I have more storage space up top, it’s only a matter of time before I load it up with tons of heavy stuff. Heavy stuff on the roof of a 4×4 is a big no no, so best to avoid the temptation altogether rather than trying to resist it. No roof rack means no roof top tent for above ground sleeping – the staple of 4×4 Overlanding.

I’m not sleeping in a ground tent for two years around Africa, and although I can sleep on my storage boxes, that’s really only a backup option for when I don’t want anyone to know I’m asleep inside the Jeep. This begs the question of the main sleeping arrangements.

Enter Ursa Minor Vehicles.

John and the crew (The Undertaker* and Tombstone*) in San Diego make a replacement hard top for the Jeep JK Unlimited (4 door) which is a pop up camper. They call this amazing feat the “J30″. The stock Jeep hard or soft top is taken off, and the new top takes it’s place. Normally the camper bolts directly onto a stock Jeep with absolutely zero modifications required, and has access hatches above the rear seat for climbing up into the sleeping section.

Of course I can’t leave well enough alone and so John and the guys customized mine simple smile

Ursa Minor J30 going onto my Jeep

Years ago when I dreamed of this Jeep, my dream was to “cut out” the sleeping section and hatches, and move the stock Jeep roll bar out of the way. Doing so meant I would be able to stand up and walk around in the entire rear section of the Jeep. Based on my photos and hand waving, a very large opening was cut into my J30, which allows walking all the way up to the roll bar directly behind the drivers seat.

The top and modifications have turned out a hundred times better than my wildest dreams. To say that John and the crew are perfectionists would be selling them short. No detail is too small for their attention, every aspect of the camper, it’s installation and use has been thoroughly considered and designed. It’s obvious these guys love what they do, and they use what they build.

With the large opening cut out, John set to work designing roll up wooden planks that are moved into place for sleeping “up stairs”. In a stroke of brilliance John made the planks so that if I choose I can install only a half width bed. The planks are held together with webbing so they can’t jumble about, and lock into multiple selectable positions with spring loaded pins. John also made mattress sections so they can be easily moved and re-purposed from sitting cushions down below to sleeping pads for “up stairs”.

I’ve spent six nights upstairs so far, and each night I’m so happy to be “up stairs” in my little house, I can’t stop smiling and my brain won’t let me fall asleep for an hour while I think of the adventure ahead of me. To say this thing is awesome is not even close to the truth.

I had a great time hanging out with the Ursa Minor guys in San Diego for a few days while they modified my top, and grinned from ear to ear when John shook my hand, wished me luck and said “Welcome to your new home”.

    Great job! I can tell you from my boat, that being able to stand up is a huge thing! Living hunched over might be ok for a week or so, by trying to put your pants on in the morning stooped over gets old real quick.

    • Dan says:

      Hey Luke,

      It’s so funny you say that, because one of the things I’ve enjoyed most about standing up in the morning is putting on my pants! hahaha

      Also, you have a boat? I didn’t know that! Do you have any pics online?


  2. Tom says:

    Looking good Dan. I was wondering what had happened to you. Love the popup hardtop.

  3. Cole says:

    Hey Dan. The Cabinets look awesome and I want to do the mod myself. Do you have an updated link or a product I cold search for on the aluminum framing? Both links provided are dead now.
    Also, are they sturdy? Anything you would change about them?


    • Dan Grec says:

      Hi Cole,

      Sorry about that. It looks like “80/20 Inc.” on Amazon has both the tube and the connectors – I have updated the links on the Jeep build page to be correct again.
      I was wondering if the cabinets would be strong enough… and they are absolutely rock solid. Even now when I rock them, the entire Jeep suspension simply moves.. the cabinets never rattle or move at all!

      Good luck, I would love to see a picture of what you build!

    So you had Ursa Minor cut out the opening larger than stock for more standing room?

    Hello Dan
    I am following your project since about a year. Have been driving with rented JKU’s in Iceland and Hawaii last Year, and searching now for owning a used JKU to built up with a J30. Destinations are: North and South America, Iceland and NewZealand/Australia (Living in Switzerland). I have three Questions:
    – How is your experience with the J30 in heavy storms (+45 Miles p.H. wind) ?
    – Was it ever wet inside after heavy rain? (side faces)
    – It is very hard to find second hand JKU’s with gasoline engine in Europe, what about a diesel engine on such a trip? Do you think I would run into severe troubles driving a diesel JKU on the PanAm ? (finding fuel, repair)

    • Dan Grec says:

      Hi Noé,
      Awesome, it’s great to hear from you!
      1. The J30 is great in heavy wind. When you park it nose into the wind you can’t even notice it, if you’re side on the fabric flaps a bit and might keep you awake.
      2. No, it does not get wet inside. the fabric is very good!
      3. I think the diesel would be fine, though I don’t know much about the 2.8 diesel engine Jeep used. I would certainly add a second diesel filter for remote places. Diesel on the PanAm will be easy to find… spares for Jeep are not super common, but there are enough countries on the pamAm I think you’ll be OK!

      Good luck, let me know if you have any more questions!

    Hello Dan

    Thank you very much for this very valuable informations. Wanderlust is growing dramatically with each time I visit your blog. But first it will take some time (1-2 years) to save enough money. My best wishes to your amazing trip. Drive save and stay healthy.
    Thank you for all those wonderful pictures :-)

    How much is for the built-in roof-top tent

  8. Joe says:

    Welcome back to the states, I’ve enjoyed following you on instagram this entire time! You’ve convinced me about the J30. I apologize if the question I ask has been addressed in one of your previous blogs, posts, or responses.

    1. Did John at Ursa Minor give you any discussions trying to talk you out of the modification such as weakening of the overall structure of the J30?

    2. Are they willing to repeat the same process for others like myself?

    3. After many years and thousands of miles, what additional things would you have done with your rollbar or J30 modifications? Or even, what would you have NOT done or done differently.

    Anxiously awaiting their KLU offering so I can start planning!

    Thanks and well done,


    • Dan Grec says:

      Hey Joe,

      Thanks for the kind words and for following along for so long! I appreciate the support and I’m happy to help with any info I can.
      Have you seen this thread on expo?
      A guy has made a version like mine but with an easier roll bar modification. I like it.

      1. No, John was not worried about strength at all. And given the abuse mine has taken, it’s not a problem.

      2. I think John is really, really busy right now with orders, and so he doesn’t want to do “custom” stuff like this. Maybe in the future. Also a few people are talking about cutting it out themselves, which should work just fine.

      3. To be honest, it’s been great, and I can’t think of anything off the top of my head to improve. I wish I got the upstairs USB ports, I maybe wouldn’t get the rear opening windows (I Just never use them), but I would get windows I Can see out of. I might also install some kind of rail on the side above the rear guard flare so I can stand on it to climb in from the outside. AEV make a good one.

      Cheers! all the best,
