So I finally built up my old trailer that I used to use to move hay around to feed animals, into a generator welder and air trailer.
Has a 7300 watt generator, air compressor with hose reel, and a stick welder. Put an 50 Amp RV plug on the front, even though I don't have the full 12000 watts , it will power enough on an RV if needed.
The poles on the back are so you can see it in your mirror behind the truck.
