I have a 1999 F250SD SB. I am looking at getting a 5er, especially since the last go around (see introduction). I have pulled several fifth wheel trailers (utility, car, etc.) in the past all of course with LB P/U's. Now that I am in the market, things have changed dramatically from the Reese 21K of day's past. I have looked at everything from the superglide to Hi-Jacker and have scratched my head for awhile and would like some help in picking the right slider. I am leaning toward the Reese 16k round tube slider, but do I really need dual pivot? I don't want to get a slider with a slide pin bar. Much prefer the dual jaw system. Comments are needed to help decide.
