As far as the tow lights, on our last two toads I have purchased 3 wire 12v bulb holders that snap in to the light housing I then drilled about a 1 1/8" hole in the housing to receive the holder. I use 4 conductor trailer "zip wire" to connect front to back with wire ties to the frame. This way the wires run from the plug at the front of the toad to the tail lights without connecting to the toad's wiring harness. If you are looking at a tow dolley make sure the vehicle you want to tow doesn't have low or excessive overhang at the front or problems might occur loading due to the tires not being on the dolley before valance of the toad contacts the dolley. Blocking the dolley to load and unload every time isn't fun.
