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.

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.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?
