Anyone out there have experience with this trailer? I have a remote cabin where I need to move alot of gravel up from the beach and the 5 gallon bucket thing ain't soundin too fun. I was going to build a trailer to pull behind a 4 wheeler with a hand operated hydraulic dump on it but I don't think I can build one for what White Spruce Trailers is selling 'em for. If any of y'al used one I'd sure appreciate your thoughts.
