I am on my second Tiffin Motorhome and would buy another Tiffin without a question. Over the past 20 years I have been to the Tiffin Plant in Red Bay, Al at least a dozen times. I have heard of no problems with the "boys" running the operations. Bob Tiffin retired, but he really never left. Bob is a "people" person and just loves being around the plant.
The biggest problem with their service is that their service is so good that they can not handle all their service in a timely manner. In the past 10 years they have opened 30 new service bays. Of course, several of the service bays may be tied up for several days with major repairs. However, they try to keep some bays reserved for minor repair. The past several times that I have been in for service I was in and out within a week. If you have major repairs you may be there for weeks. Also, don't go for service when "snowbirds" are headed north or south.
