I got my TrailAire Tri-Glide installed last summer at the big FROG rally. Several of us Creekers got a VERY good deal from Lippert on the pin boxes. I has a stock pin box on it before this. I might have been imagining it, but I could tell the difference almost immediately. And on those bad interstates with the concrete sections where we used to get that "buckin' bronco" sensation (chucking?), the difference in the ride is amazing. We will still get a little bouncing if we hit a VERY bad section, but it dampens out quite fast. But I'm convinced it is the best money I've spent since I bought the Creek!
I started out carrying about 90 psi in the bag, but deflated it to about 80 and that's where I seem to like it. Bag seems to be holding pressure well, although I haven't been out in the camper for a few months. We'll know more this summer when we get rolling again. I too carry a 12V compressor and sometimes a 150 psi pancake compressor with me. The pancake requires 110V, of course. But for the air bag the little 12V works very well. (Not so much for my 110 psi tires though
