I have a TT on order from RVW and so far the assistance and response to questions has been great. I looked locally as well, but like you the extra $3,000 to $3,500 for the same TT wasn't worth it to me. I will be making a similar length trip to pick it up so our situation is nearly identical (except you're buying a much bigger trailer).
My thoughts are if I need service in the 2 years the full warranty is good for, then so be it I'll deal with the local service place affiliated with RVW. If they are shotty or delay my service then guess what...they won't get my business once the warranty is up. My money is good all over the US and some foreign countries too
. Also I would assume RVW appreciates word of mouth business and has some agreements with Service Network they have set up. If the service is bad I will happily call RVW to complain if that's the case.
In this ecomony I wish everyone the best luck in finding the best deal they can. Retail prices are a thing of the past, this is a savvy consumer world thanx to the internet. I understand local dealers need to make a buck, but why would they pass up guaranteed money from servicing somebody else's products. A paycheck is a paycheck right.
My solution would be that if service shop keeps my trailer longer than expected or does a crap job I'll be happy to come grab it off the lot and then proceed to pass on the bad experience to everyone in the area. So for Dealers to act that way seems like they'd be shooting themselves in the foot for merely getting paid to complete a service they are charging for anyways. Plus there are always independent service and repair places like Camping World.
