2007 GMC C4500 Duramax Ambulance — Fully Converted Expedition RV | Solar | Roof
Body:
This is a fully converted, legally titled RV built on one of the most capable commercial chassis available — the 2007 GMC C4500 with the 6.6L Duramax diesel. The expensive diesel work is already done and the records to prove it are in hand. This truck spent its entire previous life as a professionally maintained ambulance fleet vehicle — meaning scheduled oil changes, documented service intervals, and no deferred maintenance. This isn't a mystery truck. You know exactly what you're buying.
Comparable ambulance conversions on this platform are currently listed at $72,000–$87,000. At $65,000, this is an exceptional value for everything that has been invested in this build — well over $100,000 in vehicle, mechanical work, and conversion upgrades combined. You simply cannot replicate this rig at this price.
