Glampervan

Glampervan is a ProMaster-focused conversion shop in Oakland, California, founded in 2015. Their core product is a semi-custom conversion on the Ram ProMaster 136-inch wheelbase high roof — a standardized layout with selectable options rather than a fully bespoke build. This approach keeps costs and build times lower than full-custom shops while still offering meaningful personalization. Upfitting on the ProMaster platform runs from $55,000 to $95,000 depending on options, with a stripped-down core build available starting around $28,000 for buyers who want to finish some systems themselves. Customers supply their own van. Build timelines run six to twelve weeks depending on complexity. The shop also does component installations and commercial conversions, including mobile recording studios and coffee shops. A team of approximately seven employees handles all work in-house at their Oakland facility. Glampervan also converts Sprinter and Transit platforms, though the ProMaster 136 is their signature. The company holds a BBB A+ rating and has been featured in Robb Report and RV Travel.
