There's so many dealers, I'm sure ev ereyone has an opinion...
Personally I bought mine from Lerch RV in Milroy PA. It's near the center of the state, so a few hour drive for you (was for me too), but a very large selection.
2 others I went to in NY state was Wilkins RV and Camping world of Bath. They're both in Bath NY a few miles apart. Between the 2 dealers they probably have 800 RVS new and used, both are large dealers. Would be at least a 4-5 hour road trip for you though.
