We are getting ready to go full time in the very near future. I have a short RV Queen mattress in my rig. It is impossible to find sheets to fit it that don't cost a fortune (in comparison to regular sheets) or are not very good quality. So, when I bought sheets for the RV bed, I bought my regular brand and have been living with the wrinkles in the fitted sheet and tucking the top sheet in where it falls out from under the comforter when I make the bed. Once in a while, I will wake up because the sheet has wadded up underneath me, and I'm sure that will continue to be a problem when we are full time.
I have seen one person post an elaborate configuration of straps and such designed to keep the fitted sheet from being wrinkled and sliding off the mattress, but that just doesn't seem to suit my style because I just don't see myself going to that much trouble.
So, tell the truth, what do you do for sheets in your RV, and does the wrinkled bottom sheet drive you crazy enough to make you wish you'd spent the extra dough on an RV sheet set?
