Hi, have been wanting to make a campervan for years, but just hated the low mpgs for something big enough. And I wanted 4wd, but we can NEVER get all these things (where is 4wd hybrid van??) Right now I am settling for a Kia Sedona, want to put bed behind driver seat, reverse 2nd row passenger seat for my easy chair. Is there 75" behind the driver seat? I know there is a sticky dimension thread, but I decided to post in the newby zone since I am new. Also, how high from floor to ceiling? Hello, and thanks.
