I had to hull a 12 foot stepladder one night and I plugged a strobe light in the 4 prong trailer connector. the truck showed the trailer mod and a light fault but wen I started to drive the trailer mod went away and all was normal.
I am going to build a dally for my tires so I can put them back on wen I rotate.
I don't know Wat they weigh but I know it's more then I wont to try to lift that way.
