Excursion is 3/4 ton. If accurate, then no concerns with nearly any <30' TT. Flush all the fluids.
My TT has never been to an RV dealer for repairs. I have never heard of a positive experience from my local dealers (or any for that matter). I do as much of my own repairs as possible. Typically when I learn of a failure, it is within 2 weeks of a planned trip. If there was a problem even if "free" to repair under warranty, the time of my vacation is worth a lot of money for me to repair myself. Order part, replace. I did have some alignment issue which I took to a truck/trailer frame shop. And I had some damage to body that I took to a auto body shop who also had experience with RVs.
