What am I missing on GVWR??

I have a Ram 3500 SRW crew cab short box. The door sticker shows GVWR as 10,100lbs. The front axle max weight is 5200, Rear 6200. Truck weight 7300lbs (diesel).

I thought the calculation to carry a truck camper was simple: Take the GVWR - base weight - passenger weight = weight of loaded camper possible.

So in my example 10100-7300-300 (us plus our dog)= 2500lbs

So the max loaded camper I can carry is 2500 lbs.
I have been looking at a cirrus 820. Dry weight of this camper is 2500lbs, but could be as much as 2800 with options. So you are looking at over 3000lbs wet which is way too heavy for my truck. I find it crazy that I can't carry a midsized camper with a 1t truck but there it is. Even the Laredo I was also considering pushes it at 2100lbs dry. These are non slide campers.

When I told the dealer I'd have to pass on the Cirrus because it was too heavy he was incredulous. He insists that he loads these on 3/4 and 1t trucks all the time and that I don't know what I'm talking about because the camper is distributed to both axles. When you look at the combined axle rating on my truck it is 11,400lb. Is this my true starting weight? Of course he suggests timbren upgrades to truck, but my understanding was that these don't increase the load you can carry,they just make that load travel better and create less sag on the back of the truck and less sway.I also thought the equipment itself has to be calculated in your total weight numbers.
I am already looking at much smaller campers but wonder why I see so many much larger campers on trucks like mine.
Insight appreciated.

  • It appears that 820 is made for a long bed? I looked at Cirrus web page and could not tell for sure.

    Many people carry 2,500 lb (claimed weight) campers on 3/4 ton srw trucks. But I would not put a long bed TC on your short bed truck. That is especially true if you also plan on towing something on an extended hitch and driving at interstate speeds.

    I guarantee you that 2,500 lb camper will add +3,500 lbs to your truck with camper, liquids, gear, tide downs, hitch, etc. Mine went from 2,700 to +4,000.

  • "He insists that he loads these on 3/4 and 1t trucks all the time..."

    Find another dealer that is honest about your truck's capacity. Does it need to be a TC? TTs are great too.
  • Many of us go by GAWR, tire and rims. We have been over on GVWR on every camper combo we have owned in 25 years but under on axle, tire and rim. We have never had any weight related breakdown, accident or issue, not even a flat tire and we have driven a lot of miles. That is just my experience and not recommending anything to anyone. Everyone has to make their own decisions and a lot of factors go into safety. I see guys pushing 80 mph with their 2500's and huge 5th wheels all the time. That scenario scares me a lot more than my TC poking along the slow lane at 60.

    GVWR to a large extent is a licensing number. I believe the manufacturers don't want to risk sales by increasing these numbers as license and insurance number go up as well. That's why Ford and Ram cap out at the exact same GVWR in their 3500 duallys Certainly one truck or the other could go above 14k, even a little bit. Look at the fight for TQ and HP. The GVWR bragging rights seem to take a backseat to cost of ownership.
  • Door sticker shows taxable GVWR, when your actual is added axles capacity 5200+6200=11400 lb.
    But with TC most of the load goes on rear axle, while not much you can do to use front axle capacity (I put generator on front to do that).
    So for your scenario you need to weight your empty rear axle and deduct it from 6200lb capacity. That will give you realistic camper weight you can carry.
    Still confirm tires are up to the task.
    When it comes to salesman BS and owners ignorance - there is no limit.
    Also realistically- the camper listed at 2800 lb will be closer to 3000, or above 4000 loaded for travel.
