Someone please help me to understand how to figure how much 5th wheel I legally can tow.
GVCW 11800 owners manual says max trailer 10,000 trailer, then says to subtract GCW from GVCW. for 5th wheel.
If I do that with a GCW of 9,000 that leaves 2800.
So is that the amount of max of tongue wt. for the 5th wheel?
Which still doesn’t answer my question about how much trailer wt. I can legally pull.
Truck is a 2000 f-350 4x4 cc lb drw 7.3 auto 4:10
Saw some where in the manual something about 20,000 max, which leaves me with only 11,000 for a 5th wheel.
Am I doing the math rite?

you could always call your local dealer then should be able to tell you how much you can tow, it also depends on what equipment your truck has..
i know with a 7.3 and auto 410's my 95 f350 is rated at 12500 lbs towing capacity, you could also check the contents section i think the ford towing guide is there..

GCWR is 20,000 pounds. If your wet and loaded tow vehicle weighs 9,000 pounds, that means the max trailer weight you can have is 11,000 pounds without exceeding the GCWR.
GVWR is probably 11,200. So if wet and loaded tow vehicle weighs 9,000, that leaves 2,200 pounds max hitch weight. For 5ers and gooseneck trailers with 18 percent hitch weight, that's a max trailer weight of 12,222 without exceeding the GVWR of the tow vehicle.
So your limit is 11,000 to not exceed GCWR, and 12,222 to not exceed GVWR. Since you don't want to exceed either one, your max trailer weight is 11,000 (limited by the GCWR of the tow vehicle).

Subtract GVW (gross vehicle weight) from GCWR (gross combined weight rating) to determine max 5er weight. Which is what we did above. 20,000 GCWR minus 9,000 GVW = 11,000 max 5er weight.
GVW is the amount of weight on the two truck axles. GCW is the combined amount of weight on all truck and trailer axles.
The GVW of the truck without the trailer will be around 9,000 pounds. But the GVW with the trailer hooked on will be way up there over 10,000 pounds and closer to 11,000 pounds. The difference in those two GVWs (with and without the trailer) is the actual hitch weight of the trailer.
Since you have a dually, the GCWR is your limiter. If you had single rear wheels (SRW), the GVWR would probably be your limiter.
You need to tow more weight than that? Then buy a truck with more GCWR. For example the 2005-up F-350 DRW with PSD engine has a GCWR of 23,000 pounds. So with a 9,000 pounds GVW, that leaves 14,000 pounds for max trailer weight. Or for 2006-up, you can get an F-350 DRW with the TowBoss option that gives you 26,000 GCWR. With a GVW of 9,000 pounds, that means a max trailer weight of 17,000 pounds. [img]/ubbthreads/images/graemlins/eek.gif[/img]

The math sounds good, if your logic is right. [img]/ubbthreads/images/graemlins/cool.gif[/img]
If that 20,000 is the GCWR of your tow vehicle, and if that 9,000 is the wet and loaded weight of your tow vehicle without the trailer tied on, then you done it rite. [img]/ubbthreads/images/graemlins/warmsmile.gif[/img]

Thanks but I want to upgrade on the trailer not the truck.
With all the recent discussion on CDL’s and weight ck’s by law enforcement, I was wanting to make sure that if stopped and they ck’ed the wt by just the GVCW on the truck and the GVWR on the trailer all would be good.
That’s what I’m trying to figure.
Looking at 5th wheel TT’s I’m interested in they are close to (but under)12,000lb’s. and thinking of getting a new goose neck trailer also. So if I get a new goose neck I would be limited to 8,000lb’s?

Remember RV's are exempt from DOT rules as long as you have an RV plate . Check with your local DOT to be sure.

That 8,800 number you computed would be the max weight on the trailer axles, not the trailer's GVWR. Not a very useful number.
First of all, "legal" will be different in every state. So talk to your local state DOT to determine what is "legal" in your state. In some states, the only thing you need to worry about is how much to pay for your license plates. Some states allow you to buy license plates that will severely oveload your tow vehicle, but you'll be "legal" if the cops stop you. In other states you can ignore GVWR and GCWR and worry only about GAWR (axle weight) or tire weight capacity.
But sticking with Ford's weight limits, and ignoring that word "legal" in your inquiry, you need to weigh your wet and loaded truck with the hitch installed but without the trailer. Subtract the weight of your wet and loaded truck from 20,000 pounds GCWR and that will tell you the max weight of any trailer you can tow without exceeding the GCWR of the tow vehicle.
Or adding the GVWR of the trailer to the actual weight of your wet and loaded tow vehicle will give you your combined weight (GCW) to compare to your GCWR.
Adding GVWR of the truck to GVWR of the trailer would be counting hitch weight twice, so that's not a good number either.
