Reputable Dealers

Im new to The RV / Travel Trailer world. Im purchasing my first trailer this coming spring. To use on a permanent location upstate NY. Ive come to the conclusion a used 5th wheel would be a perfect product for me and my use. But I've been reading nasty reviews online about some of the local dealerships I've called and gone too. Basically a lot of them say that they bought something used and things broke and were damaged and basically they feel that they were sold something that was not what the dealer said. I understand that used trailers are buy as is but since I'm new to this I'm very concerned with finding an honest and reputable dealership. Does anyone recommend a very trustworthy source for RV/s trailers, in the NY, NJ, PA, CT, VT, area? Im based in New York City but want to find honest people to buy from.
Thanks for reading!!!!!
