Curt gooseneck to 5th wheel conversion

gemarsh · March 27

The below link to gm accessory page shows a underneath photo, but I can't make out how is stays secure from spinning.

I would like to use this as the platform to make a box filled with concrete. Anyone seen or use this to help me understand?

Fist your truck must have a gooseneck hitch installed. The hole in the bed where the ball inserts is what the hitch you linked uses for securing it in the bed.

The center pin on the plate/rails you linked inserts into the gooseneck hole where the ball would normally insert. The locking pin that normally secures the ball goes through a hole on the center pin of the plate/rails. This prevents it from being lifted back out of the truck and keeps the entire assembly of rails from spinning.

It is common for the gooseneck ball to rust/seize inside the bed. If you permanently attach a large heavy weight to the rails kit you linked and the center pin seizes or rusts in place... the "box filled with concrete" would make getting it back off the truck exceptionally hard.

The truck has the oem puck hitch. My b&w ball will spin in the hole. Nothing keeps it from spinning when locked in, just a detent ball that keeps it from lifting out.

I would like to load the bed with weight during the winter months and don't want a heavy unsecured load. I would insert 4 eye hooks buried in the concrete to lift with shop crane.

I just don't "see" what keeps the conversion from turning. Is there something from the conversion rails that slip into the puck holes? If it's just a large shaft that falls into the ball hole and nothing is inserted into the puck holes where the safety chains normally hook, I'll just continue with my own design.

I was hoping there was something like the GEN-Y's goosepuck uses...

Maybe add 60 pound sand bags in the bed for weight, very common in VT. My truck has over 450 pounds in the bed (ARE and stuff). My truck weighed 8680 pounds, a little over 1000 pounds over curb weight, when I went to a Cat Scale. I don't need to add any weight for winter!

Don't forget weight in the bed adversely affects handling and braking distances. I live in Northern Ontario and honestly have never needed weight in any pickup I have owned. You would be much better off putting a good set of dedicated winter (not all season or all terrain) tires on. If you have never driven with winters, you will be in for a treat.

How do winter tires perform in mud? I have never considered them. I was lead to believe winter tires were for hi-way use.

During calving we can have dry times and then snow 2 foot deep, 4 days later it melts and it's a mud bog in the pasture. ATV's don't always cut it and they don't work well hauling a calf to a heat lamp. I know the answer, but I don't own horses.

I think I'd consider buying another kit of 'pucks'... (or lynch pins or other similar to insert in the puck openings) and cut the top off them (the ball and chain loops), and weld them to my own frame. A 2" angle iron frame, some bolts welded on protruding in to imbed in the concrete to secure it to the frame. Plywood form boards with you imbedded eye hooks. Sounds pretty simple to build to me.

And mud tires.

...come by one Saturday and we'll do it.

Two 2x4's cut to fit across the bed slots with two more 2x4's cut to fit to box it in. Add sand bags or the weight of your choice. Cheap and easy.

As far as snow tires, I've run Hakkapeliitta LT3 snow tires on my previous 1500. I didn't get snow tires for my 2500HD yet as I got the truck this past January and it came with BFG KO3's. Plan is to get another set of wheels and get the Hakkapeliitta LT3's for next winter. They are great in snow and never had a problem on mud season roads.

Agree, they perform reasonably well in mud but I have never had them in anything up to the axles. The LT3s are my preference as well (we are even allowed studs here).
