I don't subscribe to the "better to have one and not need it" sentiment. It is not better to pay more and carry extra weight for something you don't need. I can see the issue of backing a trailer at 90*, just look at your wheels when you turn. I'm not sure if it does any alignment damage but it doesn't look like it does it any good. I've parked in a couple of campgrounds where the spaces were perpendicular to the road and while I can't understand why they set the campground up like that, I still had no trouble with a SB truck with no slider. I do wonder how the non-superglide sliders work as my pinbox is relativel close to the tailgate as it is. Do you have to run one of those 5th wheel tailgates or take it off?
