1990 Prevost XL Marathon 40’ with RARE side aisle and enclosed bathroom. This luxury coach underwent a complete update that includes new furniture, new flooring, new LED lighting, new appliances, new updated UV protected front dash coverings, new invertors, new chassis and house batteries, new cell phone and WiFi enhancer, and so much more. A complete mechanical inspection and service was just completed. This coach has been well maintained because we were fulltimers and it is truly ready to hit the road as full timers or to enjoy for long vacations. Bus has been maintained by SilverLeaf Coach in Phoenix, AZ. SilverLeaf will show proof of maintenance records upon request and offer Chassis inspection service.

Well maintained Prevost and runs great.
