We have a 2014 Salem Hemisphere 282RK, and we just got a few things done still under warranty. While the dealer had it the service techs noticed that we have this problem. Tires rubbing the under side of the unit. They are currently waiting on word back from Forest River as to what to do about it. I'll post some pictures of the clearance under the slide as soon as I can. I'm not very happy with this issue, but I do have confidence in the dealer we are working with to do the right thing about it.
