I always over-engineer everything I fabricate, so I surprise myself with my answer. If you consider the 2 "Tee" areas of the bumper (where the bumper meets the frame members), imagine a 50 pound generator sitting there. That area could support quite a load. It seems to me that any problems would stem from a load that shifts and bounces, or a load that is not centered over the bumper and is cantilevered outwards. I would make something like this http://www.amazon.com/LowPro-LockDow...=lowepro+honda
or just buy 2, and mount them over that "Tee". I would cover the units with a vinyl cover to keep the weight down and to keep the weight right over the bumper. I hope this thread isn't dead because I would like to hear some more feedback.
