2006 Fifth Wheel Wildcat 28R King pin weight?

I am trying to determine the GCWR for a 2012 Toyota Tundra and have all the information except the king pin weight for my camper. The dry weight of the camper is 7900 lbs. Thanks.

No one tows an empty camper. So you'll end up somewhere between the dry weight and the maximum weight.

That said, you can usually assume 18-25% depending on how the camper is loaded.

I'm not clear as to what you're trying to determine. The GVWR of the Tundra when hitched? The GCWR of the truck/camper combined?

If you need a pin weight number to estimate you could use 20% of the camper's GVWR.

Can you provide more information?

Dave

I am considering purchasing a 2012 Toyota Tundra to pull a 2006 Wildcat (28R model). The truck is rated at 10100 and has a 4.3 rear end, towing package etc.
The curb weigh is 5460 with GVWR of 7100. I estimate the hitch at 100lbs and am trying to get the most accurate king pin weight since it is going to be close. Just using something between 16% to 20% of 8000 lbs put the weight at near capacity. I thought that there may be a more accurate king pin weight method. Really like the truck and would like it to work but do not want to end up on the side of the road either. Thanks.

The issue will be the payload capacity of the Tundra. The payload of 1640 lbs (7100 - 5460) will be with a 150 lb driver and without all options. By the time you add passengers, hitch and gear, that payload number will be closer to 1100 - 1200 lbs, maybe less. The pin weight of the camper using 20% of the dry weight will be 1580 lbs and of course loaded will be more.

I don't see how the Tundra's going to work out for you.

Edit: Another possible way is to calculate from the axle weight and the camper' GVWR. The manufacturer usually set the camper's GVWR by adding the dry pin weight to the axle weight ratings. As an example, 5200 lbs axles and a 1500 lb dry pin weight would result in a GVWR of 11900 lb. You should have the camper's GVWR and axle rating of the load rating label on the camper. The word of caution is that this would only estimate the dry pin weight...the loaded pin weight could easily be 300 - 400 lbs heavier.

And its suprizing how much wind a 5er catches. And in my opinion most 1/2 tons lack the "lead in their butt" and power to maintain a steady speed on hills and or with a head wind.
- there are many threads and posts with people buying a 1/2 ton just to trade it in within weeks or months( at a condiderable $ loss) after realizing it just wasn't what they invisioned.

Just realized how much your camper weighed. That 7900 is what my dry factory weight was- now over 10k. I pull my 5er with a diesel and I think a tundra could pull it around town maybe. I loose a little speed on the interstate and swap out my 35" tires to a closer to stock size when ever I'm going to be in hills.
- if you get the truck you will hate it for towing a trailer that size. It will be up in the rpms and droping gears frequently.
