If you order part #0004198, YOU CANT USE THE HITCH to tow. That sucks.
So if you order part #0004199, you need 3/4" clearance between hitch tube and bumper. My hitch tube is resting against the bottom of the bumper! This one won't work either.
I have the factory hitch. Is yours 3/4" from the bumper?
I guess a solution could be to put spacers on the hitch bolts, but that might have its own towing comprimises. That would also mean getting a shorter drop receiver so the trailer would remain level with the spacers installed.
I got a set at Autozone that can be mounted on the hitch or anywhere with a bolt also. I mounted mine on the bolts that hold the bumper on. You have to grind the bolt hole on the light brackets to a square to match the square head on the bolts. For that little amount of work and an outlay of $25 to $30, you get lights that work excellent and have a very wide dispersed light that allows you to see alot more that with just the stock backup lights.
The lights work so well and are so slim, that I recently purchased a second set and mounted one up behind the spare tire that shines down to light up the back 3-4' of the underneath of the truck. This works great when you have a flat on the road, for hooking up a trailer or tow strap or for night wheeling. I will enventually hook up the remaining light and maybe one more to light up the rest of the underneath for when I'm out at night off road to make sure I can clear obstacles I may encounter.
I believe Bestatchess has the same setup as I do as far as the backup lights. They set against the bumper almost like they came with the truck. As far as pics, I have a digicam on my phone that might get the job done.
