Hey Air Lift,,, awesome product, I love mine. In my particular case using the truck weekly, with varying loads, sometimes a couple times a day, the auto level feature is way to cool! Works great.
It is amazing how accurate it is. On many occasisions I have had loads over 10,000 lbs on the trailer,,,,, wife gets in the truck, compressor kicks on for a few seconds,,,,, she gets out,,,, it expells air. She don't appreciate it but I do! LOL
