Most, if not all, rv dealers are just that; the rv. In our area the dealer takes the motorhome to Freightliner for warranty repairs. Since we are out of waranty and orphaned we deal with a local freightliner garage that also services rvs. The selection of motorhome will determine which chassis the manufacturer is. There are not that many players; I know of Spartan and Freightliner. There may be others that have a smaller market share. Cummins is the only player in the under millon dollar market since Cat dropped out around 2005 or 2006. We're happy with our Cat C-7, all the power we need. We've gone cross country two or three times without any issues. We service once a year, oil change and fluids topped off and belts checked. Definitely have belts and fluids changed initially. Get an estimate but expect expensive labor rates for any work. Tires will age out rather than mileage out, The rule of thumb has been 6-7 years then replace. We pushed it and kept track of unusual sidewall cracks; when they showed up we replaced tires. We got 8 years out of our Goodyears and replaced then with Michelins and have been happy with them. No better or worse than the Goodyears. Jacks and steps are as reliable as you are as far as doing routine maintenance. Keep them clean and lubricated. As with any luxury item labor will be high and parts are usually not. We prefer manual jacks to auto leveling systems. You're asking all the right questions. Now hopefully you will get a diverse response for you to sift through. Good Luck !
