Is this normal? My B&W hitch is at the "center" position because that's what the hitch installer "normally does".
How about this: Your installer placed the hitch at the center position with your bed "unloaded". When the rear of the truck sinks some with a load, could the hitch now be slightly behind the rear axle ??

I don't have a 5th wheel (yet), but I thought they were supposed to be slightly in front of the rear axle.

3rd weighing: 5,820 + 5800 = 11,620
Diff: 60 pounds
Can anyone explain this?
What is 60 lbs. amongst friends ?? Since the truck scales are in 20 lbs. increments, and you are doing 2 axles, that might account for 40 lbs. My thought is that since the axles are so close together, and need to be at the very edge of each section, the scales may not be quite as accurate as if they would have been centered on the sections better. That's my story, and I sticking to it.

I would say yes....the 2 need to be added together to get your total weight.

2280 lbs. (corrected) divided by the total weight of 13,840 gives you a 16% hitch weight.

Great job on getting your weights !!!

Chap-

I like and can agree with your answers.

I can't say anything about how the guy did the fifth wheel. I think he literally went with the "middle" position "just because". I'm going to look around for some other folks weights to see what they say.

The 60 pounds makes sense, too- I didn't realize the scales were 20lb. increments. And, you're sure right- I was at the very edge of both scales. Between the narrowest part of the tires is only an inch and a quarter or something.

I still feel like 16% is pretty low for a fifth wheel pin weight. I'd always heard 20-25%. Crap- I might not have needed a dually!

1a) This is especially interesting in that our "payload sticker" stays that we have 4,297 pounds of available payload when the truck came from the factory. This means that our weight, my add-ons and our stuff weighs 1,197 pounds.

I don't think the sticker includes the weight of 35 gallons of fuel & the other liquids added to your add ons (hitch bed cover etc.) 1,197 sounds about right. Esp with all the stuff you have to have for the kids The kids stuff probably weighs that by itself........

I did think it included a full fuel tank, but doesn't include any occupants (including driver- based on wording in the manual).

The add-ons would be the turnover ball gooseneck hitch, the Companion fifth wheel hitch, Retrax pro bed cover are the biggies. Figure 700 pounds of people weight and then the 2 car seats. Plus a variety of guides, foods and activities for the kids.

It all adds up. Very enlightening! I never would have guessed I'm as close as 800 pounds to my GVWR on a dually (even if it's a Dodge).

I have installed a couple of 5th wheel hitches and GN hitches before, and I always placed center of the hitch 2-3" forward of the axle. I also know that the local welding shop installs GN hitches 2" forward also. I was always taught that a GN or 5th wheel hitch was supposed to put a little bit of weight onto the front axle.

From what I understand the pin should not be directly over the rear axle, and definitely never behind.
Ours, is a full 4 inches in front, but I think that is about maximum.

That's the thing- I'm definitely UN-loading the front axle by 20 pounds and have the numbers to prove it.

I've also had some situations where it feels a tiny bit squirrelly - almost like sway was happening (but mirrors confirmed it wasn't).

I think I've decided - I'm going to adjust the hitch forward and see how it goes. If any fifth wheel owners have scaled with and without camper, I'd love to know your front axle weights.

Mine is the factory ford hitch and it is 2" forward of the axle. my 14K 355bhq puts 60lbs on the front axle by my CAT measuerments.

Thanks Lynkage- we have similar sized campers. It's good to read.

I just wish I knew better where my axle is in relation to the hitch. I'm going to have to crawl under tomorrow and check it out.
