Looking for camper weight advice!

Sorry I didn't know how to title this thread specifically enough, and it's a long form questions, but here we go.

Before I get started here is a list of useful info regarding the rig we plan to outfit with a camper. The truck was scaled with the factory hitch with me plus a full tank.

2008 Chevy Silverado 3500 CC/DRW Duramax
Firestone airbags
6 Firestone Transforce tires rated for 2535# Each
Torklift Superhitch w/ tie downs

GVWR: 11,400#
total Curb weight ~7,840#
Steer axle weight 4,480#
Drive axle weight 3,360#
GAWR RR 8,200#
Tire load limit RR 10,140#

My girlfriend and I are planning a trip to Truck Camper Warehouse in the near future to look at two different Arctic Fox models we are considering; the 811 and the 990. Yesterday I had done a lot of research to figure out what the "real world" loaded wet weight is on these two AF models since AF is very reticent with their claimed dry weights by leaving out their "mandatory options". I found that people were claiming roughly 4500 and 4700 lbs respectively for these two models and I found this surprising. To give you guys some perspective, I've crunched some of the numbers above to find out "on paper" what my weight limits are.

"tolerances"
GVWR 3600#
GAWR RR 4840#
tire load limit 6780#

I'm perfectly fine with being over the GVWR, as this seems artificially lower considering the axle ratings and what the tires are rated to carry. However, I wanted to hear some of your thoughts on where the limits truly lie. I bought this truck specifically for the purpose of hauling a camper and towing our 6x10 enclosed trailer and it seems like the weight of the Arctic Fox campers put them into a very rare class of trucks. I simply don't see that many 4500/5500 trucks out there.

In my head our first camper should weight between 3800-4200 lbs fully loaded. Is this completely unrealistic? Am I over thinking it?
are the Gross axle weight ratings artificially low as well? If so, how close can you get to them, or how far can you safely exceed them?

I would like to know who out there has had experience with a similar rig and what they found when they went to the scales. If it turns out the Arctic Fox models are simply too heavy, we will likely end up with our first choice a Lance 975 or 995 since they actually publish a wet weight for their campers with standard equipment. Hopefully THEY'RE not hiding their weights too. Also we are planning on using the camper as much as possible. We are looking to get out at least one weekend a month over spring/summer and we plan on taking a week long trip south and southwest in early winter. So, suffice it to say we're not just going to use it "occasionally".

Thanks in advance!

  • The AF811 will be about 4000 lbs when loaded and filled and the 990 will be about 4500 lbs.

    The AF811 long bed version will have almost no overhang and allow you tow without a receiver extension or maybe one that is 18" or less if your trailer has a short tongue. The 990 will minimally need a 28" extension to clear the rear due the rear wings that contain storage and the generator compartment. Your trailer sounds like a 3500 lb model which will put an additional 350-500 lbs of tongue weight on the rear axle.

    The rear axle in your truck is made by AAM and has a 10,000 lb rating, but GM derates this axle due to their suspension choice - Your rear wheels have more than enough capacity and are fine under heavier loads.

    You will most likely find that the springs are too soft and will need some help. You can preload the springs faster by using using blocks or wedges to keep the same spring rate but get less sag or you can add additional suspension components to to carry a heavy load. In either case I would suggest a stabilizer bar on the rear axle to reduce sway and check your current shocks for dampening ability.

    My wag on GVW will be 12,500-13,000 lbs with about 8000-8500 lbs on the rear axle once you are fully loaded up and hitched.
  • Typical error on this forum is comparing taxable rating, not real vehicle rating.
    Since most of TC weight goes on rear axle, the calculation is child's play.
    As you already posted you have 4840lb rear axle load capacity and tires have more than that. That basically will carry any 8' camper and most of 9' campers, even when you pack them heavy.
    But sounds like you are planning to pull a trailer and heavy trailer on stinger will add hefty number to the play.
