I installed Firestone Air Bags on the Dodge today. I didn't take any pictures because it was pretty straight forward and truly a "bolt in" project. Just follow the directions and allow a couple of hours for the whole job. Wait! You will have to drill a couple of 5/16 inch holes for the valves so you can add air to the bags. I placed ours on either side of the licence plate.
Our camper's tongue weight squats the truck and I can now level it for better control and shift the weight bias.
Since I have a generator and small air compressor, I chose not to buy the on vehicle 12 volt air compressor that is optional. You "air up" the bags to carry a load and "air down" the bags when not pulling the trailer.
Could we have done without them? Yes, but I feel safer with them installed. It's like the 15,000 hitch I installed, just adds safety and piece of mind and my mind needs all the help it can get.
