Doing a little research I have found where a lot of those trailer mfgs. have a F rating with the BBB or no rating at all.
Xtra Tuff F, Hurricane Cargo F, Freedom Trailer B-, Colony Cargo A, USA Cargo A, Axon's trailer sales A+, Elite trailer NO, Imperial trailer No. Cargo Craft NO.
That may be partly due to people buying at the factory and not receiving support with problems. Like one guy said you can pay 2,000 more at a big dealer and then you might get more support.
