From my CT conversion sketches, this can be fit into a 7' x 16'-18' space, so it won't be something you can tow with a small vehicle or hybrid.
Size and amenity wise you described my log cabin and a whole host of other CTCs. My cabin measures 7 foot wide x 14 foot long, overall height 96 inches with 72 inches interior in the center. That was achieved with a boat trailer frame that had downward arched cross members. The trailer overall trailer length was 20 feet so I have additional storage and room for a generator there, but otherwise 17 foot would suffice. Ground clearance with 15” wheels is 12 inches.
Now mine was built primarily for the style but a streamlined version could be made. I am reminded of the couple from Irving ? Greg and Terry ? (can't recall their name or find any old posts) that had the oversize teardrop with the drop down floor and a full size sleeper sofa.
You may recall my full size murphy bed is fully made up and easily swings into position and is 24 inches from the floor making entry and exit easy. I have hanging closet space behind the bed, ample storage in the lockers below which also double for seating and/or table or desk top.
I have a full kitchen with 8 linear foot of countertops, 10 linear foot of upper cabinets, 6 feet of lower, freezer/fridge combo, microwave, pod coffee maker (for the new wife), propane oven w/3 burner cooktop, 24x36 combo shower and toilet, a propane tankless hot water heater, and 8000 BTU air conditioner. I think I have about 8 gallon grey water and 12 gallon black water tanks below the floor. Now I was in a bit of a rush to build so used standard size ready-made cabinets but with your wood-working skills could make much more efficient and lighter.
I am towing with a Jeep Liberty, so not a compact, but not a full size pickup either.
