I have a set of Firestone bags for sale. They were on my truck for about 3 months but never used to tow. I was going to purchase a toy hauler and bought these. Things changed and Im not going to be able to get one for some time so I took the bags off. Everything is perfect. Air lines were cut to run through the frame to the 7 pin plate where the valves were mounted. If anyone is interested PM me an offer.
