I tow a 31' travel trailer (6038 UVW), and I also pick up a 1 ton pallet of wood pellets in the bed of my truck. Having the AirLift 88299 LoadLifter 5000 series airbags installed on my truck makes leveling my truck simple (I also installed the AirLift 25980EZ compressor which makes airing up and airing down the airbags as simple as it gets). Installation of the airbags is pretty straight forward, just follow the included instructions or watch the video AirLift has on their website. There really is no need to have them professionally installed, if you can change your own oil and are familiar with some hand tools then you can install these air springs. Please keep in mind that airbags do not allow you to carry more weight in your truck bed or tow more than what your vehicle manufacturer recommends, they are just a tool to help you level your truck when you have heavier loads on. The best part is no more sagging bed!!
