I plan on starting a new teardrop style foamy 5'x10'+ camper. Using a TSC 5x8 mesh floor trailer with 13" tires. With cross-way beds and drop floor. The floor plan will be front to back A 30" cot with a bump out for my feet. Then a 10" deep drop floor with a commode on one end. then a second 30" cot(half a queen). Galley wall with a roll up Tonneau pickup box cover as the galley hatch. The bump outs will be big removable storage tubs. That will be put in place when parked. The roof will be 3 2'x5' solar panels One for fridge. two for CPAPS and lighting. Walls will be 1 1/2 foam with PMF and 4 1/2' tall. With a front profile like the 2+2 with the 20" rounded front for the front cot to fit mostly in.

Is the Carry-on trailers any good for the price(on sale now $640)?
