I bought my hitch from a guy in Colorado who makes them, not chrome and powder coated black, cost 2 yrs ago was 125.00. I pulled an Aluma for over 4000 miles in 2009 and it was fantastic. The only problem I had, was riding in hard rain, the lid did leak a little, but a little more foam gasket and it wouldn't leak. I don't have one right now but am considering the Harbor Freight trailer for 199.00 and find a roof pod and make one. I just can't see paying 2-4000.00 for something I might use once or twice a year. Just my opinion.
