I am looking to put a generator on a folding cargo rack on the hitch of the TT when I get it, I want to also be able to run it while it's back there (good idea or bad) because I plan on building a cag...
Be aware that mounting the gen to the frame will cause vibrations through out the frame of the TT and you may hear/feel them while inside. I put my gen far away from the TT and chain it to a tree - use an extension cord to connect to the TT. It's already a quiet Yamaha gen but this way I don't even hear it.
On occasions that I have had the gen close to the TT - I can smell exhaust fumes.
