got my weight ..ouch

See if this is correct ..

i weighed my truck with all my stuff ect..= 7650
GVWR of truck is 10,500
GCWR of truck is 18500

18500 - 7650 = 10850 maximum GVWR ( i guess) of trailer.

10850 isn't much if you are looking for a double slide 30' fiver is it ?

If my figures are correct (please correct me if i'm wrong) I might be better off looking at a trailer instead of a fifthwheel..

If the above is true....how is anyone legally pulling the larger fifth wheels with a one ton dually?...there can't be that much difference in ability to tow from one year to another can there ?

My truck is 1998 dodge 5.9L turbo diesel 4:10 rear , automatic

thanks for your imput...i'm somewhat discouraged

This weight business is confusing...

sorry REWahoo, he's correct. The GCWR is the Gross Combined Weight Rating, which is the maximum the truck and trailer together can weigh, and he's computed it correctly.
The only correction is the the value daydreamer computed is the maximum GVW that his trailer can have - it can have a larger GVWR (manufacturer's gross vehicle weight RATING) as long as he never loads it by beyond a GVW (gross vehicle weight) of 10,850. Check the website you pointed to - it correctly computes the total weight of truck and trailer to compare against GCWR.

Yep! Your correct. That is the dilemma with older trucks. Your weak point is going to be the automatic transmission. Keep your fiver purchase around 32-34 feet maximum length and two slides and you should be good to go. Even older duallies have more capacity then it looks like on the surface.
Heck my newer dually scales ready to go at 8000 pounds and my fiver has a scaled pin weight of 3000 pounds. So that puts me loaded at 11K with a 11,500 GVWR
trailer scales at 13,500 with a 13,750 GVWR. But I have the 6.7L, the 68RFE 6 speed automatic and 4.10 rear end to help me out.

New DRW 1ton trucks have a GCVWR of 30,000 lbs with the max tow features on the truck, but they also kicked them up to 800 ft lbs of torque with a 6 speed transmission. They also have an integrated brake controller on them that works SWEET with the exhaust brake of the Cummins Diesel. With a scale weight of 21340 combined, I had to drop to 10 MPH on a steep hill, and the turbo picked right back up on the uphill pull and passed the semi that cut me off on the uphill pull.

Two answers to your question/comment.

First: Many tow their very large 5'ers and TTs witih way too little tow vehicle.

Second: IN another family of forums there used to be a poster with a photo of his tow vehicle in his sig file.. The sig was "There's no replacement for Displacement"

The tow vehicle... A Peterbuilt Semi Tractor.

I have seen a few of 'em towed that way.

As you know.. Old truckers never die, They just get a new Peterbuilt.

So then i should be looking for a fifthwheel with a dry weight(?) that allows me to have a gross vehicle weight of 10850 or less ??

sorry but i want to get this right..

this forum is fantastic...didn't have the original post up 30 minutes before getting all this response.

dry weight is a useless rating. as soon as you put anything in the trailer that weight is out the window. it is best to use the GVWR of a trailer in your calculations unless you are absolutely sure of how much stuff you will put in it.

I would not be afraid to go up to a fiver with a GVWR of around 12K with your dually. BTW what transmission do you have??

You have a old stout 3500 DRW truck for its era. Size of the 5er of your dreams depends on the trailers "wet" pin weight and its gross weight.

Diesel trucks back then were down on HP/torque compared to todays new gen diesels. Your '98 probably is the 180/420 engine compared to todays new gen diesels at 400/800 with 13000 GVWRs and those big 9350 RAWR for carrying big rear axle loads compared to the '98 DRWs 7800 RAWR (approx) .
Todays 3500 DRW have upwards of 21000-22000 lb tow ratings compared to your '98 DRWs 10000-12000 lb tow ratings

Question; "If the above is true....how is anyone legally pulling the larger fifth wheels with a one ton dually?..."

There are a couple of Legal issues that size and weights officers looks at. One can be if your state has a certain gross weight requirement when you register the truck. Some states like mine have no weight registration requirements.
The only other legal issues is staying under the lessor of the trucks rear axle/tire capacities for carrying payloads. Your trucks rear unladin weight may be approx 3100-3200 lbs. Subtract that from the trucks 7800 RAWR leaves approx 4500 lbs for a payload. All weights depend on actual scale weights and the trucks actual RAWR numbers.

Don't be discouraged. There are lots of 5th wheels out there in the weight range for your truck. I think you'll find that some of the newer 5th wheels are built a little lighter for the longer lengths. Wait until the end of the year, you can get better deals. Good luck and don't get discouraged.
