I also tow my 5-er with a short bed, no slider (B&W Companion.) For the most part, it works well, but you can jacknife any combo--slider or not. I had an "small" incident similar to OldTool2, but I didn't put that big of a dent in my cab, didn't damage the front cap at all, and didn't break any glass (I was lucky.) Backing out of a truck stop parking spot, at night, in a tight spot in the lot. Bottom line--keep an eye on the angle, and you'll be fine, slider or no slider.
