The engine and drive chain have been checked out by a local mechanic, oil changed, spartk plugs changed, spark plug wires replaced, all fluids changed, and wheel bearings checked and greased as required. Recently driven on 250 mile road test and worked perfectly. Generator parts replaced, but needs some work to work under load. Back up camera needs checked. Jacks work, but need some adjustments. All 6 tires are new before the 250 mile road test.
