Hmmmm....
I am picturing an inTech motorsport trailer, big enough to put the Jeep in, with a flat extended tongue like ours so there's no need for a hitch extension.

Outfit it with some cabinets/desk up front, nice RV style windows down the sides, A/C on the roof, some fold down benches/couches on the walls, an extra set of doors in the rear to keep the A/C in while you have the ramp extended out horizontally as a deck when camping, and a bunch more solar on the trailer roof. Roll out some carpet when the Jeep's not in there and you'd have tons of room to "work".
Could even do like we did and get tanks added to the trailer. We have a 90 gallon fresh and a 50 gallon gray (why I didn't do 90 on each is beyond me - might see if inTech can upgrade that at some point) with a water pump in the trailer for the fresh. I can transfer fresh water to the camper and transfer gray from the camper to the trailer to extend our range.
One thing I thought about but we didn't end up doing is putting a people door on the front wall of the trailer. We have cabinets on the inside there, but that'd let us walk out the back of our camper, step on to the tongue and just walk inside the trailer. When we extend our camper's rear awning it's practically a covered breezeway anyway.
Maybe you should check out our trailer when you are up in the area.
