Deere:
I have had the single bag from Kelderman on my rig for about 3 years now and have found that it made a big difference in the ride. It also makes it easy when I hook up to my camper. I just add the amount of air that it takes to level things up.
At first I was concerned about putting in too much air in the bag,
and was told that the bursting pressure was 300 lbs!!!
