    is my GMC 3500HD diesel denali pkg SWR 4x4 enough to pull a 2016 GD Momentum 397TH?

    We just purchased a 2016 GD Momentum 397TH and have a 2020 GMC 3500HD Diesel Denali package SRW. Will this truck be enough to pull the camper fully loaded? we also have 2 Polaris Sportsman 570's to load in the garage, will this help take some of the weight off the 5th wheel hitch to help alleviate? New to pulling this heavy of a camper, we had a Wildwood by Fleetwood bumper pull camper prior.

    What is the cargo carrying capacity listed on the sticker inside the driver's door?

    That won’t be the problem number. You’ll be under that but most likely over the payload number loaded for travel if that’s important to you.

    I’m guessing you somewhere around 3800 payload and the 397 is about 3400 empty. That leave around 400lbs for people, pets, hitch, propane, batteries any cargo in the truck or trailer. A loaded garage will pull weight off the pin but not as much as you think.

    Edit: saw your updated post, 300lbs at best completely empty. You’ll need to weigh it to see where you’re at.

    In short, probably not. Read this thread from beginning to end:

    https://www.mygrandrv.com/forum/show...ing-Capability

    With a 20,000 lb. GVWR, when loaded the 397TH could put up to 4,600 lbs. on the pin. You then have to figure in the weight of a hitch, passengers, and anything else you would put in the truck. That trailer is firmly in dual rear wheel territory.

    Sorry to tell you, but you won't even be close to staying within the payload numbers for the truck with a 397TH. They are not too much less than your truck's payload number when the trailer is new, and empty. There are plenty of folks out there with the 397TH and pin weights are many times in the 4300 to 4400 lbs when they are loaded up and ready to camp. It is a trailer that needs a Dually without question.

    NO, don't even think about it.. That's a really heavy 5er even empty, 15600 lbs for our 2021 and loaded will be 4000 or better pin.
    I have this TH and wouldn't ever think about towing with a SRW. That said ,it's a great rv.
    Also I don't know your location but check your DL rules for these heavy gvwr combo's . Several states (Tx for example ) require a class A or B non-cdl to legally tow combination gvwr over 26001 lbs. Not a big deal to get, just something that might need to be obtained

    20,000) your trailer weight will be between the last 2 numbers and can only be determined by WEIGHING your trailer.

    Your truck's "listed" payload is simply the GVWR minus the actual truck weight (sometimes the manufacturer includes a driver) when it rolled off the assembly line. EVERYTHING else you add to the truck (people, tools, hitch, bed liner, bed cover, etc. reduces the listed payload value.

    You specifically asked if your truck could handle a Fully Loaded 397 which would weigh 20,000 lbs. 20-25% of that weight will be seen on the truck as the "hitch weight". that means you will be putting 4,000-5,000 lbs of weight on your truck. You will definatley exceed the GVWR (max value the TRUCK is rated for) since as it left the factory it was only 3,701lbs away from the GVWR.

    You don't list what the RAWR is (Rear Axle) but you are probably over that even further than you are over the GVWR. Rough math puts the weight your rear axle will be carrying at
    (12,100 - 3701 = 8,399lbs for the truck alone as it rolled off of the factory floor. split approx 40/60 between front and rear and your empty truck is at approx 5,040carried on the rear axle. Add in the 4,000 lb hitch weight and you are approx 9,040lbs on the rear axle (some will transfer to the front but not much) Add the rear axle's portion of the stuff added to the truck listed above and you are pretty close, if not over to 10,000lbs on the rear axle. Definitely dooley territory.

    When Chad and Tara, from "Changing Lanes RV" still had their 2017 397TH, their pin weight was almost always in the 4500-4600 lb range. Granted, they are full timers and have a lot of stuff that they carry, but they also had a Victory motorcycle that was 900+ lbs in the rear as well as all their computers, office equipment, etc

    Our truck, Ram 3500 DRW, weighs 9,770, loaded for travel, with tools, passengers, an extra 15 gallon of fuel, and fifth wheel hitch, but without the RV. The weight distribution is 55/45. However, the front axle is is carrying the 55% and that is with DRW and a loaded bed. The rear axle only weights out at about 4,400 lbs. The OP's truck may be 40/60, but the 60 will be over the front axle, not the rear. His empty truck is probably closer to 3,500 over the rear axle. The OP is still well over payload, but I don't know about the rear axle limit.

    For misc info, when we add the 3,600 lb pin, the front axle only gains 45 lbs.
