Last time we drove to Burning Man we built a bed in the back of the van (full instructable here). If you were wondering if we could reuse the same bed in our new van, we can!
While Sally, the GMC Savana 3500, is longer and taller than Bertha, the interior is actually narrower in certain parts.
We trimmed the bed's joists and plywood top, and now it fits perfectly.
We also adjusted the bracket holes to make use of the GMC's seat locking mechanism.
