I put a nice B&D 800 Watt inverter under the hood mounted on the firewall. Then put a separate outlet dedicated to the inverter in the cab area. Worked fine. Gave me 7 amps for stuff. Easy to find a place to mount, wire, and check on. Also added a off on switch with light next to the driver to operate a solenoid near the inverter. I'd bet there'd be a mounting situation near the back bunks. Maybe in a basement compartment.
But...500 hours per year is only 10,000 hours over 20 years. There's nothing wrong with that. A well maintained genset should get at least 10K hours before overhaul. Usually 20K.
