Google "swing out for salt spreader" It will show Snowex PPT-175. These are swing out arms that are 37inches long and have a plate that is drilled to mount a salt spreader on. You could put the generator in a box and bolt right to the bracket. Watch the weight. I think these are rated at 175#'s. Also on Amazon type in StowAway Hitch Mount Swing Arm. If you expand out the photo's you will find one that shows mounting strips at you could bolt a plate or box to and secure your generator. This one is rated at 250#'s. The prices on both units are around $200 to $270. My friends set their generator on the ground and chain it to the van. Last week in Cali while they were sleeping, someone cut the chain and drove away with it faster than they could get out of the van to catch them. I guess thats the cheap way to get a Honda 2000. Good luck with what ever you choose. These are both cheaper than I can have one made. But the home made on would be stronger.
