Anyone running airbags on the rear of their 4X4??? Took the truck on a 2hr journey last week and took 2 atv's in the bed and my 16' fishing boat on the bumper and boy the old girl was sagging in the rear....brakes and steering where fine so I was thinking about adding air bags in the back to assist on such occasions....What do you think??? If anyone is running airbags where did you get them as I can't seem to find any kits specific to our years but have found them for the 73 up generation.....Thanks....
