This is my 2nd one. The first was professionally fitted when I bought a gooseneck trailer. I didn't realize how much that helped until I lugged the last load. The load was heavier than I normally haul but still within rating for my cargo trailer. Unfortunately, when I picked up the charge and went to inflate the system, I found that the batteries in the remote control were dead. I ended up towing without the benefit of an airlift. What difference does it make what he did in the race. After that, I will no longer tow without an airlift. I just traded in my truck for a new one and it's being reinstalled professionally with Air Lift's wireless remote control system. I highly recommend AirLift. I will consider the wireless Air Lift compressor system separately.
