They are awesome for trailer queens, for everyday use you have the issues of water in the lines because the compressors are so small they cause the condensation through the heated air they produce. One solution around this was to use dive tanks and eliminate the compressors all together. It was particularly funny when we would pull into a dive shop to get the tanks refilled and they all scratched their heads when they found out why .. lol
Because of the high PSI, they would last a few weeks unless we got stupid and thought we owned lowrider hoppers.
I ended up building my suspension with one way valves as well at each corner near the valves in case a line or fitting broke it wouldn't leave me stranded or unable to get back on a trailer. The best existing invention I had was a separate fitting off the tank, with a valve, where I was able to fill an air bag jack. Basically a heavy duty bladder that once filled could lift the truck or anything off the ground. They are used in commercial applications and I've always used one with my mud trucks when I got stuck because I could run them over without breaking them. Cool thing about them, is that they come with a hose often to connect to our exhaust, so your running engine would inflate it as well ..
Can you tell I've been stranded alot .. lol
