Way to low to the ground. It'll never work for boondocking.
There is more than one way to get standing interior height, and low towing height.
I decided to get what I wanted I had to go with a hard sided pop up. I want standing height inside, queen bed, shower, toilet, indoor kitchen, hard sides, and winter usability. But I also want easy towing so I'm going with a hard sided pop up that has as much streamlining as reasonable. The shower and toilet must be usable without folding the bed up. Interior is 11' 2" long by 5' wide. Length dictated by keeping it short enough that 144" x 36" and 144" x 48" aluminum sheets can be used for wall construction. Kitchen counter, cabinets, etc. are done with modules that can be hung on the walls. The bed will fold into a couch along the back wall, or side wall. Haven't decided that yet. The trailer is only an inch wider than my 4Runner. For scale, the cowgirl is 5' 8.5" tall with heals and hat, and the vehicle is a '95 4Runner.
Top down. It's under 4' 6" tall sitting on 31x10.5xr15 tires, and has over 12" smooth clear ground clearance.

Top up, but the transport door panels are still in place. The top lifts 58" giving it a 78" tall interior. Door height is high because there is a 12.75" high basement area for utilities like furnace, water heater, battery bank, water tanks, etc..

I have some more images in my gallery as the design has evolved. I don't have a design thread yet as I haven't thought of what to call it.
This shows the floor layout, except the toilet is now along the front wall instead of angled in the corner. It collided with the door in it's stowed position when the top is down. Green box in the corner is the size of an Engel MT45 Refrig/Freezer. It is from an earlier stage in the design and a number of details have changed.

The disadvantage of this design is added complexity and cost. Also when raised, the trailer is narrow so it is more susceptible to side winds. I've made the design so I can make the core box first, then add the front and rear streamlining later. The utilities are also be designed for adding them in as budget allows.
