A little off topic, and I haven't read the whole thread (I peek in from time to time), but is there such a thing? One of the AWD SUVs I am considering can only tow 1500 pounds with a tongue weight of 150 pounds. My dirt bikes won't fit inside the SUV, and a hitch carrier with bike(s) will weigh a lot more than 150 pounds, so I would need a trailer. Open trailers are okay, but I would prefer an enclosed one to keep the bikes out of the public eye (one is expensive, the other kind of rare) so no one is tempted. I was wondering if there was such a thing as a trailer that would weigh in well under 1500 pounds (with two dirt bikes that total 500 pounds) and was enclosed in some fashion. It doesn't have to be a a Wells Cargo type enclosure, just something that encloses the bikes - probably a plastic shell of some sort. I saw this, which is the closest thing I came across: http://www.ironhorsetrailers.com/thetrailers/1biketrailer.html Even though it says it is a one bike trailer, I bet I could get both my bikes in there.
