I am looking at getting a set for my truck. I have only heard of 3 companies; PacBrake, Air Lift, and Firestone. I have only really compared the PacBrake and Air Lift but am wondering about all systems that may be available. I would like to add onboard air, maybe a 2.5 or 5 gallon tank along with controls for the air bags. I know nothing about air bags, and plan on doing the installation myself. I like the PacBrake set up and the onboard options, but Air Lift has a nice system too and a wireless remote. I would like to know opinions of anyone who has a system, or has done research on them; plus and minus's would be appreciated. The search function did not give me what I was looking for. Currently I am towing about a 10k set up, tractor and trailer. The ride is not to bad, but I have heard it can be better. I plan on adding an auxiliary fuel tank / toolbox combo and that is where I can put the 2.5 gallon tank or two. Any concerns on the pump and locations for it? I would assume heat will be an issue. I would prefer to keep the system in the toolbox area, our ranch roads are several miles long and dirt on top of that. Well, now I am rambling, thanks for any info and pics if available.
