I took a mount that curt makes for the rear bumpers of travel trailers, designed for 4 " square tubing. no welding involved. then i went to onan & got a 2600 lp generator, took & fabricated a plate for it to bolt to & attached it to a reciever extenion tube & slid it into the curt hitch. then i ran a 12 volt wire from my panel to the gen set , protected by a auto reset 12 volt fuse , ran a gas line from under my trailer to the gen set . then ran the 120 volt wiring to an interior recepticle , made modifications where i could use shore power or generator power depending on which plug i used. topped it off with a remote control to start & stop it from inside the trailer, nice at night when u are watching tv from the bed. i cna give you more detailed instructions if you need, but i have used this set up on 4 different trailers since 2001 without any problems.
