The short answer: The HEST Dually Custom S is our camper van mattress, built for Mercedes Sprinter and Ford Transit vans. It comes in two sizes, the Custom S60 (60" x 68") and the Custom S75 (75" x 68"). The curved end sits between your rear doors whether they're open or closed, and a horizontal bi-fold lets you fold it during the day to make room for gear. Measure your sleeping area and compare it to the two sizes to pick yours.

Airstream Basecamp 20
One Basecamp 20 owner told us he and his wife are very happy with their Custom S, and that folding it gives them access to a rear table and storage compartment. He also noted it's about 12" shorter than the Basecamp's bed area, so measure before you order.
