Query: Works Great, Easy install

I purchased this about 5 months ago for an 09 Ram 1500 with rear coils. I have towed a 27' and a 30' RV using the bags and they work great. With the rear coils the back end of the truck was very low even with the weight dist hitch. Adding these brings the rear end up and makes towing a lot easier. The install was easy for me. You do not need to take the coil off on the Dodge. I just jacked the truck up by the frame so the spring extended, took the tire off and was able to push the bag into the spring. Probably took me two hours start to finish for both sides. I would definately recommend. I have been towing with them inflated to 25lbs and I leave them at 15 for normal driving to stiffen the rear.
