I bought a 2" mattress topper thinking I wouldn't have any issue closing my SomerSet E3 PUP. Well, it wont close. I mean I can probably force it, but i don't want to as the door handle will rip the topper for sure. So I can roll it up and put in door way, but that leaves me with only 1 comfortable bed... Anyone have any suggesttions for an Air Mattress? I cant seem to find any that fit a RV King size bed?!?
