I didn't like the fact that the liberty cargo area isn't flat with the seats down. It is also a little small for me to lay down in the back while camping. Here is my platform I build to sleep in the back.
It is a four piece design that can be stacked and removed when not used. Used 1/2" plywood covered in carpet w/ padding. Used 2x4's for the rear piece. The piece that is over rear seats connects to rear piece and lays flat on front edge of rear seat.
This view is with front seats in normal driving position with rear gate closed.
This view is front seats all the way forward with platform headrest down and rear brace slid out. I used drawer brackets to pull out 2x4's for foot extension for when rear gate is open. I still need to create a bracket or legs to hold up head rest from falling in rear foot wells.
All pieces in place for sleeping. Obviously I can't crawl in from the back. I don't think my extension would hold up.
And last all pieces stacked for removal or travel
