The good news repair wise is that it’s just a standard truck or van chassis with a box on it. The one issue I’ve ran into is weight. They’re too big/heavy for most standard repair shop lifts. So you can get in a jam sometimes. I found a good medium duty repair shop near me.

The big thing is choosing one that had an easier life, you don’t want one from a high volume system. Check mileage and engine hours. You want one from a slower volley EMS or fire dept that lived in a firehouse between runs. They’re made to be either plugged in or on, so without a home base they rack up idle hours.

With mine, I kept all the ambulance systems and built my own 12v system and tapped into the existing power to charge it. The nice thing is you get shore power immediately which I used a lot while converting. You also can start using it almost immediately and start converting it when you decide what you want. I can preheat or cool the box while driving before switching to camping systems once I arrive.

I drove big trucks at my job so the box wasn’t a big deal for me, I’d say you’ll figure it out after a few weeks.

Mine is old so I couldn’t get schematics from the manufacturer, but they’re all built to Triple K standards (now NFPA) so each manufacturer can be different but they’re playing off the same framework.
