Cautionary tale of my recent experience with the service department and extended warranty (not Good Sam). Went in on 4/22 with list of 3 things to fix, two of which involved replacement of Winnebago OEM installed items. As Camping World is a Winnebago dealer I trusted that the would have parts source for their products. I took my rig out of their service department on 5/8 with neither of the OEM parts replaced. Reason? Camping World was sourcing the parts retail and then marking them up 70% and extended warranty company refused to pay. Camping World justified markup and explained that they unfortunately don't have a wholesale source for Winnebago parts and that I'd have to make up the difference out of pocket if I wanted the repairs done. So, if your repair requires parts and you have extended warranty you may be in same situation. BTW, warranty company was willing to pay keystone 40% markup. CW didn't budge. On repair that was done to fix a leak involving the roof mounted A/C the service tech left oily footprints on the carpet and A/C panel fell on floor as I pulled out of their lot. On the repairs that were not done, one involving the OEM Nav system, the dash panel was replaced without reconnecting wiring harness to door locks, emergency flashers and rear defogger which I didn't discover until I tried to unlock my doors. This doesn't begin to express my frustration with the experience of dealing with a company that really doesn't seem to care about customer satisfaction and service. You are forewarned.
