I have a 2024 gmc sierra 3500 with a 45ft flatbed trailer and I do hotshot with it I initially had just the 7500 xl helper bags and I just added this compressor and it's the best investment I have ever made very comfortable and love how easily I can adjust the air pressure loaded and empty , I really recomed this item .

Well, I got it installed. Removing the old system was the worst part. I replaced a old Airlift system that was dying on me. This unit saves time using the EZ Mount that the compressor, and controller is installed onto. The pricy Wireless Air is required for a truck bed camper so each side can be controlled. Since, I am towing a fifth wheel trailer, the less expensive Wireless One works just fine. Over all, the control is much better than the previous version. I am glad I made the change.

Easy install. Hardest part was finding a good out of the way dry spot. Wiring super simple, one air line to connect. Only issue I had was it said it had a leak somewhere and would keep running. Read on forums that the factory fittings on the compressor side leaks out of the box. Double checked everything then triple checked and it was good. So something had a tiny leak..maybe my fault maybe not. Either way have used it a handful of times and super happy with it! Easy app connection too
