Thanks for all the great advice, I'm goning to begin working on it in the next week or two. I'll be sure to post pictures and maybe a how-to guide.

I'm trying to figure out how to put a large bed in my red 1997 pontiac bonneville, I'd like to remove the backseat, then feed the bed through the trunk and onto where the backseat was located (I'd build a frame for the bed to remain level)

Even after removing the seat there is still a barrier ...
