rather than drop five posts into the middle of a new thread out of order, i am leaving the link and letting you three start clean. nothing was deleted and nobody is in trouble. this was just the wrong room for it.
the question on the table: 2020 ram 3500 crew cab, 6 foot 4 bed, single rear wheel, 3,460 payload on the door sticker. 41 foot front living fifth wheel, 16,800 GVWR, scaled at 3,280 on the pin. empty bed, no hitch yet. go.
pullrite superglide, and here is arithmetic instead of opinion.
on a 6 foot 4 bed with the hitch set over the axle, the kingpin sits roughly 42 inches ahead of the back of the cab. the front corner of a wide body fifth wheel swings on a radius of about 54 to 60 inches depending on the cap. so the trailer meets the cab somewhere between 60 and 70 degrees of turn, which is a normal back in at a state park and not a stunt.
the superglide gives you twelve inches of travel and it takes it off the kingpin as you turn. no handle, no getting out, no remembering, and that last one is the entire product. pullrite publishes a cab clearance chart by truck and bed length at pullrite.com, so look up the ram and settle it in two minutes instead of two pages.
what it costs you: about 1,500 for the hitch, right at 200 pounds installed, and it sits tall, so the trailer rides nose high unless you flip the pin box. the bed is gone for hauling anything, which on a 6 foot 4 bed it mostly was anyway.

b&w companion with the slider, and i will say why in shop terms.
it drops into the under bed gooseneck setup half these trucks already have, the head lifts out in one piece at 105 pounds and the base at 65, and when it is out the bed is flat and empty. the ball is a forged four inch thing i have never seen fail. the slider is manual, which is the honest complaint: you stop, pull the handle, make the turn, push it back. people forget. i have taken four pin boxes off trailers this year that got driven into the back of a cab, and that repair starts at 900 and climbs fast if the front cap cracked.
what i will not do is bolt an aluminum funnel under a 16,800 pound front living trailer and tell a customer it is fine. the paper ratings are fine. i am talking about what rolls into my shop on a lowboy.
then let me be the data point that never rolls into your shop, ted.
andersen ultimate, 35 pounds, bought in 2019, 40,000 miles behind a 16,800 pound pinnacle, texas to michigan to arizona with a lot of gravel in between. it has never been serviced because there is nothing in it to service. one greaseable ball, one funnel, one safety pin. it is the only hitch i have owned where you cannot hear the hitch.
two things you actually have to do. torque the ball nut to spec and check it, and grease the ball and not the plate. people skip both and then blame the design. it does not slide, so on a short bed you either run the offset version or you learn your turn angle.
and the thing nobody in the other thread wanted to touch: prescott is 240 over on payload. 200 pounds of superglide against 35 pounds of andersen is 165 pounds of his problem solved by the hitch choice alone.

somebody go measure instead of arguing. it takes a tape and five minutes and it ends this thread.
park the truck straight with the tailgate down. measure from the center of where the kingpin will sit to the back of the cab. write it down. then stand at the trailer and measure from the center of the kingpin to the outside front corner of the cap. that second number is the radius the corner swings on. if it is bigger than the first plus about four inches of mirror grace, you need a slider, or a sliding pin box, or you accept that you cannot jackknife it.
my 337RLS behind a 6 foot 9 bed is 46 and 51, and i have creased nothing in eight years, though i also back in like an old man. prescott, post your two numbers and we can all go to bed.
long bed lurker question. i am on a 2500 with the 8 foot bed and a 38 footer, and i have never come close to the cab, so i have always assumed sliders were a short bed problem i get to ignore forever.
if i move up to a 40 foot front living trailer behind the same truck, does the wider front cap change that, or is eight feet of bed enough that i never have to think about it?
