No matter what I am going to be over in the payload/kingpin department. I can accept that since I have a SRW truck. I will feel comfortable as long as I don't exceed my axle or tire ratings.

This is at max load. I don't think in the real world I would come anywhere close to this. I figured 4 quads in this measurement, when in reality its more like 2 quads, 1 bike, and 1 mini quad (those weight a total of 1,030)

By those numbers, I know you realize you will be overweight but so will your rear axle....IMHO I wouldn't pull a TH with a 2500/250 SRW that size...The dry pin weight will almost max what you have available on your GRAWR. You may be able to find a good one thats an UL....maybe not as big and with all the gucci toys inside but will suffice. As well, I just traded in my 07 2500 for a 12 350 as the deals right now are really good. Your call though but I wouldnt think that risk would be worth it.

Kevin,

As you know from my signature I have a 2008 GMC Sierra with a Duramax engine and the Alison Transmission. While my GVWR of the truck is 900 pounds less than yours (yours has a box frame and mine has a C channel) our tow rating is about the same (15,300 pounds 5th wheel trailer weight).

My truck is maxed out towing my 9300 pound 5th wheel because of the 1500 pound pin load coupled with my family, dog, generator (in the bed), hitch, and spare fuel.

With another 900 pounds of payload available pin in your truck and a 20% pin load, you can add another 4500 pounds of camper.

This should make your maximum trailer size right at 13,800 pounds and no more.

Your plan "B" camper is also way too ambitious as well, IMO. Look for something in the GVWR range of 13-14,000 if you plan on using 100% of your truck's available capacity. 12-13,000 for a safe pad.

It has been my experience that you will use 100% of camper payload eventually.

Well I like to be ambitious
Thank you for your help!

Its my understanding that triple axle trailers reduce some of the pin weight. Is this your experience? And if so, is the reduction amount anything to call home about?

Axle count should have little to nothing to do with pin weights. The axle placement would. Think of it like a seesaw. You have a load spread across a fixed distance, but where you place the balance point, or fulcrum, determines how much leverage you will get from either side, thus effecting the balance of the load. adding an extra axle would only disperse weight over the axles, so with 2 axles and 10k lbs, you would distribute that 10k 4 ways with a fairly balanced load (minus pin weight of course). With 3, you sould just spread that load over 6 points, thus lowering the load on each individual tire. as long as the fulcrum, load weighting, and distances stay the same, the leverage remains equal at each end.

Make sense? I hope I got all of that right...
