Pin box

Just took delivery on my 1st 5th wheel. A Grand Design 150 series with a Lippert Turning Point pin box. If I was to install the wedge and move my pivot point back 22", could I go on the highway with this setup ? Or is this just for getting in and out of tight spaces.
Thank you.

Need to know what hitch you have. Some hitch mfrs. will void their warranty if you use one of these types of hitches. B&W, in particular.

Interesting timing on this. Was at a RV dealer yesterday and asked about these pinboxes as half of their inventory had them.
The sales person didn't quite sell me that they understood how it worked and it turns out that they didn't understand it at all.
Info on the web repeatedly states that they are not for aftermarket installs.

Part of the reason a 5ver tows so well is the fact that the king pin is on or ahead of the truck axle. Your pin box is designed to be used with the wedge but using it will cause your 5ver to not handle as well as it would with the pivot point ahead of your truck axle. If you imagine towing down the highway and turning your truck to the right; if the trailer pivot point is in front of the truck axle your trailer will also start turning to the right with the truck. If you have the pivot point 20 inches behind the rear axle when you turn your truck to the right the front of the trailer will start moving to the left slightly before being pulled to the right ...... you may feel a little trailer sway using the wedge.

That is what it is designed for........changing the pivot point for everyday towing.

Unlike a slider that moves hitch/pin back in bed of truck for manuvering only

Lots of people roll down the road with the kingpin locked out. No issue at all for them.
