Ben removed all the seats and he and Jon cut and bolted 2x4 's and plywood to the existing metal frame of our car.
The back section is stationary (for storage) and the front half is removable ( with storage underneath) so we can adjust our seats when not using the platform for sleeping.
The original platform was 5 inches higher, but after much consideration for our comfort we decided to lower it 5 inches.
We bought a 4 inch memory foam, blankets and 0 degree sleeping bags.
We have a ton of space and were even blessed with the use of a car top storage unit by our friends neighbors.
Here are a few photos from that past few days of construction and prepping.
