I will bet you that the majority of the designers have never been in an RV before let alone used one. All you have to do is go to an RV show and look at the different models. Last year DW and I went through a rear bedroom 5er, the dresser drawers would only open about 6" because the bed was in the way, you couldn't walk past the dresser and the bed, plus not enough room to put anything in the drawer. It should be a requirement that every designer has to live oin an RV for a year before they can design anything
