You just gave me an idea: You know how some folds pour their rear weight boxes full of concrete, with various diameter PVC tubes set in? How about pouring the concrete in around two trailer receiver hitches (with an appropriately-sized loop of 2" receiver-strength square-tube piping down deep in the concrete, for strength)? Then, one could weld up a variety of tool boxes/trays/frames to fit those two receiver hitches.
Dumb? Overbuilt? Under-thought? :laughing: Love to hear anyone's thoughts,
if this isn't too big of a hijack.
