Anybody here have any experience with living in their car while traveling? I'm going to be traveling across the country in a few months and I'm trying to make a good setup for the back of my Rav4 but I keep seeing what seems like ads for these foldable bedframe/storage things.Is there something I'm missing with these? It seems impractical in the sense that you lose what little headroom you already have if you want to sit up and the storage requires you to get out and go all the way to the back of the vehicle and open the door to access it.Is there any reason I should consider getting one of these instead of just getting a single trifold mattress and having storage on the side of it?Any other tips would be appreciated as well as this is my first time making a trip like this
