If you are looking for a deal on a quality, brand new trailer contact Fastload trailers in Tampa. You should be able to get a top quality new aluminum I Beam trailer with brakes on two axles for about $5000 or so. They can deliver but not sure of the price.
They are building me a trailer at this time. I checked with literally everyone and have bought about 15 trailers in 4 years for my boat side business. I have seen just about every design and maker. Fastload has been around 17 years and is run as a family business.
