I went a different direction and I used a cargo tray on the back (but plan to put hitch on front) and I bought a 3500 propane generator.
I already carry 15 gallons of propane (but only run one tank at a time) and I carry a 5 gallon bottle loaded into a plastic milk box and it rides in the bathroom.
If I need the generator I'll have plenty of fuel that's so much easier to carry and use, with gas the carburetor might gum up if you don't run the engine dry and clear out the **** they put in gas these days but with propane it just starts and runs.
Mainly we use the 5 gallon bottle with the tree where you can top it with a lantern and run a grill and stove.
SO with a propane bottle I can pretty much do whatever I need to especially if we're off the grid.
