As a long time anti air bagger I too now have them!! I have way too much junk and combinations to haul them. The overload springs were just not cutting it anymore. With the TC the ride was OK but the TT was just enough to engage the overloads and the ride was very harsh. And I can put more air on the heavy side of the TC.
On a recent trip back from MT I had a Razor in the back and towing my TT. All was good until I hit a section of concrete road. Bang, bang, bang on the expansion cuts!! Had to pull over and let air out a couple times till I got it right then air back up once on the asphalt. I decided then the wireless compressor was in my future.
Now being able to adjust for different load and road conditions on the fly is worth it to me.
