I have owned rv's for over 50 years and never had worst warranty service. My 5th wheel has been in shop for one month. I made an appointment for service 2 months before I brought it in expecting them to start soon after I dropped it off. Their SOP is to put you in the cue when you drop it off! No need for appointment. They will get to when they can. I called yesterday to check on progress and was told that my service writer was gone. I asked the service guy I was talking to about my status and he started reading a list of repairs that was for some other rv. I asked him to findout the status of MY rv and call back with correct information...over 24 hrs no reply what so ever. Thier shop is 50 miles from my house. I have a DeMontrond dealer 10 miles away in Texas City. Problem is they don't service DRV rvs. That was a factor in my purchase...close service. Should have checked it nout. By the way Thor recently bought out DRV witch severly limits the number of shops that will do Thor warranty work.I have travel plans that they are aware of. I will call them now and remind them of my pickup date on way or the other. Based on what has happened so far I beginng to doubt yhey are even capable of doing the work I need.
