On bed length, one way to overcome this is to remove the plywood over the under-bed storage and install a piece 5 inches longer or whatever you need/want. Then get a full length foam topper mattress and cut it to length. Won't matter if the plywood overhangs a few inches over the end of the bed frame. Bottom sheet doesn't need to be an exact fit.
Will only work of course if the TT layout has enough clearance at the foot of the bed or entry to the bedroom on either side of TT.
This *could* open up the possibilities for finding a TT.
The other good thing as of late is all the units that are coming out with arched ceilings. Great for taller people.
