Technically, I have a ford aerostar minivan and not a pickup truck, but the way I've outfitted the back is very similar to how I"ve seen most pickup truck setups. That is one sleeping platform that takes up the entire back and storage underneath. I'm 6'3" and would like to be able to sit up in bed. <br><br>So, long story short. I'm looking for some kind of pad or mattress-type-thing that:<br>-fits in the back of an aerostar<br>-provides half decent support<br>-is not too thick (as to save head room)<br>-is cheap<br>-is big enough for two<br><br>I'm thinking some kind of foam? Any help would be greatly appreciated.
