Lock n roll installed today, I got the new version (I believe it is the 500 series, so 5th rev?)
Pretty diesel build and design. Had to drill new half inch holes in trailer, but no problem otherwise. I got he vehicle side with the 2" drop or 2" lift option. As the trailer sits right now, will have to do a 2" drop, if I put the bigger tires, will have to do the 2" lift, but then I can't open the rear door with the trailer connected Shouldn't be much stored in the truck anyway.
