My boat came with a galvanized ShoreLand'r trailer and I am very happy with it. I added boat guides, a spare tire carrier, and LED trailer lights. I think there is a dealer in the Portland area. Here is their web site: http://www.shorelandr.com/
Tricker Trailers in Lewiston Idaho. Simply the best, and when I got mine last year they were almost $600 cheaper than Stevens best price. They were also the only ones that would upgrade to electric brakes at the same price. I shopped for 7 months and compared everyone from Tricker to small mom and pop trailer companies, and the guys at Tricker gave me a great price for more trailer anyone else had.
I bought an EZ-Loader trailer from the Northwest Boat Center. They are located on N. Marine Drive just off I-5. They are an EZ-Loader dealer. They saved me over a $1,000 from what I was quoted by North River. The trailer from North River had brakes on only one axle, and the one I got has breaks on both. Both places qouted me the price for the same exact trailer.
