Is anyone towing a Montana High Country 305 rl with this vehicle. I'm a little concerned about the pin weight of 2270 lbs.

[stengels]

Year and how they built the back end would be necessary to know for sure.

I have a similar vehicle to yours, mine is a 2015 Denali with Duramax and Allison. I have had my truck on the CAT scale, full tank of fuel, 5th wheel and heavy duty bed cover. Front axle = 4580lb, rear 3360lb. GM axle max is front 5200lb, rear 6200lb, but with a total combined of 10,000lb.
Say your driver, passenger and cargo comes to 400lb, you can assume equally split between front and rear. IE 4780lb front and 3560 rear. The rear axle is capable of a pin weight of 6200 - 3560 = 2660lb. However, should you load to this amount you have exceeded GM's combined weight by (4780 + 6200 - 10000) = 980lb
In your case you will be close to 4780lb front and 5830lb (3560+2270)rear for a total of 10610lb. Within axle loading, but high on the combined.
You need to get your rig on the scale. Now that I have taken delivery of may new trailer it will be on the scale before my first trip.
The year of your truck can also be a factor, between 2015 and 2016 GM significantly reduced the 5th wheel towing capacity. I suspect there was no change to the truck, but possibly conformance to the SAE or some other national standard.

2015 2500hd chev/gmc vs 3500hd capacity's are very similar, 3500 can carry more pin weight but the total tow capacity goes down slightly. As far as brakes, engine, frame and such like equipment all identical however the suspension in the 3500 has an extra spring. No differences otherwise other than options available, not as many standard or available on the 3500. I opted for the 2500 as a result, installed firestone air bags as I had in my 2006 2500hd and I'm towing a Montana 3790RD no issues at all. I've had a Commercial Ontario AC/Z class (transport truck/bus)license for 30 plus years and I see no need to have a bigger truck as I use it for multiple use not just hauling the 5'er. The HC Montana's are lighter so I expect you won't have any issues at all with your truck and that pin weight. If you don't like that the rear sags slightly from its regular none loaded position put some air bags in it or add a spring and your done, both cheap options. In reality the difference if purchasing a new truck is less than $1000 bucks to go to the 3500 but as I say you lose out on some nice options and thus I chose the 2500......good luck

[speedster100]

2015 chev/gmc 2500 & 3500 capacity's, there will be variances based on equipment, cab styles and srw vs drw that change the ratings which you have to look up but as a general starting point here is what you are looking at. The sturdy chassis and heavy-duty suspensions contribute to greater payload and towing capabilities, compared to previous models:
•Maximum available payload is a segment-best 7,374 pounds, up from 7,222 pounds
•.Maximum available conventional towing is also segment leading, at 19,600 pounds with the available factory hitch – up from 18,000 pounds.
•Maximum available fifth-wheel towing is 23,200 pounds, up from 22,500 pounds.

Thanks everyone for the responses, very helpful. My truck is a 2007, so my capacities are likely less than the newer models. My manual gives me a payload capacity of 2689 lbs, I assume this is before passengers and fuel. So allowing 400 lbs for passengers, 260 lbs for fuel and 150 lbs for the hitch, I'm left with a net payload of 1879 lbs. It is this that concerns me about towing a trailer with a pin weight of 2270 lbs.

[whiterose]

These are GM's specifications (Lbs) for the 2500HD, standard box, 4wd CK25743. This is the vehicle type, quoted in the original post.

Model year: 2016/ (2015)
Rear axle: 6200/ (6200)
Front axle: 4800/ (4800)
Kurb wt.: 6533/(NA)
Payload: 3144/ (2793)
Gross veh.: 9500/ (10000)
Ball towing: 13000/ (13000)
5th wh towing: 14200/ (17100)
GCWR for 2015 model is 24500lb

There will be some minor changes based upon individual vehicle specs, but nothing like the numbers in the above post.

Basis of my weights is GM's online published data: "Seirra HD Automatic transmissions", "2015 brochure" and "2016 Online Order / Reference Guide". Dealers did not have the 2016 brochures when I last checked two months back.

GM are claiming 18000lb 5th wheel for a 2500HD, but that happens to be a 2wd work truck.

I too have taken delivery of a 3790RD Montana. Advantage of this is the underfloor rear storage, that can be used to reduce pin weight. Keystone claim 28% pin weight, but elsewhere they recommend 15 to 25%.

[speedster100]

The storage space is awesome back there and they put the water tank at the back as well, I find the unit tows better with a full tank of water. As we boondock constantly I usually have it full when we leave the house. The truck handles the trailer with no issues, it squatted about 2 inch's (slightly more than it did with the CF345RF Cruiser) so I popped in the Firestones and I run about 15lbs of air and it just takes the weight with slight squat and sits perfectly level. As you say with the storage space a couple moves of tool box and barbeque etc for simple balancing of ride depending upon load. The 2013 Crossroads Cruiser was packed full in the front storage and I expect the pin weight was more on that one than I have now due to rear storage.

Most posters have missed the point that this is a 2007. GVWR is 9,200, cargo capacity is on the sticker on the driver's door...not in the manual. That "payload capacity" is just that TOTAL payload capacity...pin weight, driver, passengers, extra fuel, cargo, everything in the truck. I looked at this truck prior to buying my D/A dually...a Montana was (is) way too much for this truck.

[08UltraRider]

Previous truck and 5er was a 2010 Chevy 2500 HD D/A with airbags pulling a Montana HC 343RL.

Truck Sticker 9,200 GVWR and if I recall correctly the dry pin weight was 1,970 pounds.

Doing this from memory... I did scale them ready to go where I was over the truck capacity by about 1,000 pounds... 4,700 front, 5,500 rear. Was still under the tire and axle capacity.

Truck pulled it fine but I did end up moving to a dually.

[bigskyjimmy]

TLightning is right Gang you are talking about 2010-2016's etc.. the original poster has a 2007 2500HD LBZ DMax/ Allison and yes he will be a little over on pin weight and that is why I got the 2007 3500 Dually D/A Crew Cab Long bed,But he does want to tow a High Country which is for sure lighter than our Bigger Monty's and he will not be crazy overweight or anything ,If he was trying to tow a Big Monty then heck No

[bigred715]

I have a 2007 3500 SRW extended cab and the GVW is 9900. The difference between the 2500 and 3500 is 700#. After adding the extra spring the real difference is less than 700#, so I didn't gain that much from a 2500. The real difference is going to DRW. I tow a 3000RK with 2 slides at 35 1/2' and fully loaded I am about 400# over my GVW.
