camper bed a bit claustrophobic, anyway to get over it

I had the same problem, could not sleep in the overhead bed even on the outside, I hated getting in an out of the bed besides that. We traded it in on a 5th wheel, was a nice class C camper but between the bed and the grand kids staying with us it was just to small. We moved to a 33ft 5th wheel with a king bed, slept well after that, was still pretty small with grand kids sleeping on the pull out sofa so moved up to a 41ft, now we have room Yahooooooooo
