We have been looking for a trailer too, and looked from the Mississippi this direction for the last couple months. What we have found, is that most dealers stock trailers that have sold well in the past for that dealer/region. This may or may not be what you want though. Maybe you want bare bones, fully loaded, a certain color, certain length/width etc. Not to mention all the finishes, accessories, axles, etc options that you can go through. In our opinion if you are looking at buying new, and have the time, it is hard to pass up just having a trailer built for you, the way you want it. We got several quotes, and they are actually pretty reasonable, and when you get it, it is done, no extra money invested.
With that said, if you are not too picky, and looking for a great deal, the snow shows usually have some killer specials. The Puyallup show always has several trailer vendors, as do most of the shows in the west.
