I agree and then, I don't agree. I believe, and I don't believe. We purchased a used 2720SD. I needed a number of parts, which were shipped (and billed for) quickly by Adam (2006 to 2207). I was very appreciative, and told him so.
Then we traded the 2720SD in on a 3326 (2008). I ordered (called, e-mailed, etc) Adam to get these parts (for the 2720SD) (decals and outside shower parts) quickly so that I could give the dealer the best 2720 he had ever taken in. Trust me, I hate to give or sell something that isn't "right."
We have the 3326, have camped 95+ days since last Oct, but I'm still waiting (and most likely, so are the new owners) on the parts which I ordered at least 6 months ago. SO - I'm still waiting for Adam's early super-service, and I haven't had to order anything since then.
I'll tell you how our 1st return trip for warranty repairs goes, shortly. I've been told that they will "fix what they can, and order parts." When we took delivery of the TM, they (Dealer) said they would "order parts, and call us when they were in. (so as to fix everything, all at the same time, I reckon")
