I have owned the sx1800 for about 8 months now and just got back from our 7th trip(2 included dumont) and I am more than happy with it. I easily fit 2 quads and 2 dirt bikes with room to spare. Keep in mind this trailer is 20 feet long with 14 feet of cargo space to the first cabinet so if you are clever you can fit quite a bit. I shopped around for about 4 months before I bought it and found one up by Chico, Ca for 14,500 otd(minus ac and generator). The trailer in nice and light and has the ability to carry a lot of weight. You will be more than happy, but I would shop around for a better price.
