I understand and I am pretty nibble but it is a wrestling match....and hubby has to make his bed up in the "loft" over cab. I like room to sleep and move around without clobbering him.
I use sheets and try not to change them too often:E
I start with the far corner and go from there. I tuck everything in well and with just one person it doesn't get messed up much. Just flop the quilts back and consider it "made". Hey I am on vacation...actually I don't make my bed our bed at home either as it is upstairs and don't see it again until bed time.
Sleeping bags are too much of a pain for me. Your next rv will be a walk around!
