Congratulations on your new Tiffin. Hope you have many happy times. I bought my coach in Michigan from General RV and am from PA. Also a 30% discount from Tiffin's MSRP supplied to me from the dealer. Before I bought I called Tiffin and asked them about getting warranty service in PA. They told me to find a place I like and just tell them to contact Tiffin first before doing any work. I took it to Camping World who took care of it without any of the You didn't buy it here crap. I asked them if they had any problems with Tiffin and they told me that Tiffin is really great to work with and had no problems.
Precisely the reason I bought a Tiffin.
