Upgrade Your Camper Van
Electrical & Solar
Upgrade an aging or undersized power system with lithium batteries, additional solar, a larger inverter, or other electrical improvements.

We install pop-tops and service existing systems, including canvas, seals, lifting hardware, and other components that wear with time and use.

Our cabinetry is designed and built in-house around the van and the way you use it.

FAQ’s
-
Yes. A significant portion of our upgrade and service work involves vans built by other conversion shops or their owners. We review the existing work first and confirm what can be done safely and practically.
-
GTRV builds on Ford Transit, Mercedes Sprinter, Ram ProMaster, and Toyota Sienna platforms. We also evaluate upgrade and service requests for other professional and DIY camper van conversions.
Send us your van’s year, make, model, and conversion details so we can confirm whether we can help.
-
A pop-top is a roof section that raises up to give you standing room inside the van, then folds flat when you're driving or parked. It's what keeps a van garageable while still being comfortable to live in. Pop-tops are our specialty, and about half of the people who contact us are asking about them.
-
Yes. We regularly work on electrical systems installed by other builders.
Common projects include converting from AGM to lithium batteries, adding or replacing solar panels, installing or resizing an inverter, and correcting charging or power problems.
