We have also had good service from LD in both Tampa and Tucson. We bought in Tampa two years ago and got a great deal on our MH and had a good experience doing it. We returned for service a year later as we were driving through and again had a good experience -not perfect - but good.
I prefer to use Freightliner for chassis repairs and routine service. They are also easier to find as they are nationwide.
I've also stopped by the coach manufacturer, Tiffin in Red Bay AL, for a few repair items. You would only go to Red Bay if you wanted to stop by Tiffin. The Coon Dog Cemetary is about the only nearby attraction.
