Bass Ackwards KS First Shot Design for a 40" Wide?

Based on a small 40" wide by 6' 8" long utility trailer that used to be a small popup.
It's designed for a single person and meant to be ultralight, and pulled by a Toyota Corolla with a max tongue weight of 75# (that's why the A/C is in the rear).
The sides are 7' 4" by 3' 6". I'm thinking the height might could be reduced a couple of inches.
I already see the A/C will have to be raised, and I misspelled 'tongue'.
