When I was looking at the different models of trailers out there, I was more than confused.
The two you're looking at are very comparable, with the Gulf Stream being a little less expensive. When I was looking and found models that were similar, I started asking questions as to what materials were made in construction, how were the aesthetics, what sort of "quality" was put into fixtues, faucets, etc. While you might get a better deal on a GS price wise, it may or may not be saving you money in the long run when it comes to replacement or repair of items I mentioned. Take your time. This is the time of year when deals are out there.
