I want one to use for a few different applications plus hauling 2-5 bikes. Have been looking at 8.5x18 United Trailers and Intech. Nice ones all aluminum spec out around $13 - $15 k. Aluminum with wood floors and walls $9-$12k . I don't know enough about them other than a couple I looked at got real flimsy when I pulled a 7700# truck into it. ( had to prove a salesman wrong!!) so my main question was anyone's experience on what to look for quality or build wise. Looking at these things is like comparing Vespa vs HD!!!
