By "floating down the road," I mean that it feels like the tail wagging the dog.
As far as weight Distribution goes, I don't know how to adjust it. We have adjusted the sway bars to put more weight on the hitch, loaded the front of the trailer, etc. It has the same feeling when pulling a small trailer with a mower on it. So far, I haven't found anyone, mechanic or RV guy, that has been able to help me. Everyone I've had it to says it is typical of that kind of air bag suspension. I'm pulling my hair out trying to get this straightened out when I have yet to find anyone who can physically help me.
I was also told that my trailer could have a bent axle. While in getting some other work done, they said it was fine.
I did pull it with a Chevy 2500 and if it masked the feeling, then fine. It rode beautifully and pulled like it wasn't there. I appreciate all of the suggestions and help, but I am clueless as to how to do the WD adjustments.
