When the back seat is out or folded there is still the seat belts and seat belt mounts, and the seat brackets which make the floor not useable for a large ice chest. I have an ice chest that fits perfectly except for the seat brackets and seat belts but if I build a raised platform using 1x2s and 1/4" plywood it will raise the floor and make it smooth for cargo. Before I build it just checking to see what others did, maybe there's a better solution? (A smaller ice chest is not an option)
