warramty work on new 5th wheel

Who is your dealer? As I also live in Michigan, might be able to give you a reference to a better one, if I knew where you live and who you went to.

What type of issues are you having? For items such as fridge, a/c unit, awning, furnace, water heater, toilet, etc. you can take it to most RV repair centers rather than to a dealer. Those items are covered under their own manufactures warranty such as Dometic or Norcold rather than the RV's manufacture. Thus, you do not have to take it to a dealer. Most RV shops will handle component warranties.

You still have to go to a dealer for service on the trailer itself, walls, roof, plumbing, slides etc.

Contact your warranty rep for Columbus and discuss with them. You may have the best luck taking it to a dealer who handles Forest River products, but not the Palomino line.

That is a question to address to the manufacturer, but even if they say yes be prepared for a dealer where you did not purchase to put you at the end of the line for service. He will take care of his own customers first and I do not blame him.
