When we received delivery of our 2016 BH 3160EL the first time we retracted the opposing slide outs the off road side was so poorly centered it jammed hitting the ceiling fan. The dealer had to adjust the slide forward by more than an inch to get to operate properly. After taking the trailer out and working the slides we noted that the slides do not close uniformly flush against the sides of the trailer. Again we took the trailer in for adjustment. The shop told us they did the best they could but that the slide out was designed to close that way. The top of the slide out is so tight that the trim is bent out, while the bottom edge is out far enough to slide 4 fingers between the gasket and the side of the trailer. Is this normal? Are they not supposed to close flush to the trailer? Do I need to ask the factory?
