a buddy of mine is buying a new 2008 3500 single rear wheel .. what is the LEGAL amount he can actually tow with that truck .. he pulls a 28 foot Arctic fox toy hauler bumper tow ... it weighs approx 14800 lbs... any info would be great .. he is getting conflicting reports fro the dealerships ..

Here is a website for up to a 2006 model but it should not not be that much difference. Hope it helps.

 

cool , thanks for your help ...

Towing capacity = (GVWR) - (weight of cargo, passengers and fuel)

Pin weight is further limited by whether the trailer is a bumper pull or 5er/gooseneck. The bumper hitch has its own limitations, and if it's a 5er/gooseneck, you need to consider axle and/or tire limitations as well.

All in all, a 3500 SRW will have around 2100 pounds for pin weight assuming the truck with passengers, fuel, and in-cab cargo weighs around 7800#

 

Not to flame, but that is not right. Towing capacity will actually exceed GVWR (which is 10,100 on my truck.) Tow Cap on the 2007's with the 6.7 was about 13,400 for the 3500 SRW, so the 2008 should be about the same.

The different cab configurations have different payload capacities, so that may affect the payload available to handle the tongue weight or pin weight for a particular trailer. For example, my 30' TT weighs about 7700 wet with a tongue weight of about 900# +/-. I use an Equalizer W/D hitch and the bumper stops are still 3-4 inches off of the overload springs with the trailer on.

I think the published payload for a SRW Megacab CTD is about 2600#. (Reg Cab and QC's are higher.) My actual payload available is 2840 based on actual scaled weight of 7260# dry.

I suppose you could calculate GCVWR - actual weight of the truck and come up with a tow rating also. Keep in mind that GVWR, axle capacities and tire ratings need to be considered also as previously mentioned.

 

Legally is the key word here guys. GVWR and GCVWR are not legal numbers. He needs to be concerned with GAWRs and tire weight ratings.

those specs are for a dually i believe the GVWR for a SRW should be 10,100

 

No flame, just good discussion.

The disconnect here is that you're going with advertised numbers like "payload" and "tow rating", and I'm going by GVWR.

Weight of the trailer virtually doesn't matter at all. What matters is how much of that trailer weight the truck bears, and how the weight is distrubited. Any heavy trailer is going to bust your GVWR way before it reaches any advertised number like "tow rating".

For instance, my old 5th wheel had a loaded weight of about 10,000 pounds, 25% of that on the pin. My GVWR was 9900 pounds (3500 SRW), and the weight of the truck loaded with passengers and fuel was around 7800 pounds. That means I had 2100# of GVWR left to play with, and I busted that by 400# with a "light" 10,000# trailer. The weight was well within the axle and tire ratings however.

If my old 5er had a different weight distribution (less on the pin), then it would have towed terribly and dangerously. If it were much heavier, I'd be breaking GVWR by a wide margin, and probably approaching the limits of my axle and tire ratings. That was pretty much the limit of my truck.

I did the math on many different trailers when buying my 5er. A 14,000# trailer is the realm of a 4500-series truck or beyond if you want to stay within numbers on door stickers. For those who don't care too much about the stickers, most duallies can tow and stop the load just fine anyway.

Bottom line:

Tow rating and payload are advertising gimmicks
GVWR, axle ratings, and tire ratings are the hard numbers if you care about them
Many don't care and do just fine anyway

 

^^ the numbers I used above were representative of my truck configuration only (I'm not saying all 3500 series SRW trucks have a 2100# payload capacity), but I wouldn't expect other configurations to have any more than a few hundred pounds difference

Those numbers were from http://www-5.dodge.com/vehsuite/TowingGuide.jsp
and was for a srw qclb 6.7 68rfe with a 3.73 rear.

well i looked at that page and it said for dual rear wheels right at the top....

this is what i got when i put in long bed, quad cab 4x4 6.7l and 6spd auto...

With 11.50 Axle for Dual-Rear-Wheel Vehicles and 4.10 Axle Ratio You Can Tow 15350 lbs
Gross Vehicle Weight Rating(GVWR)[i]=12200
Payload[i]=4704
Curb Weight[i]=7496
Curb WeightFront/Rear=4454/3042
GAWR[i]Front/Rear=5200/9350
Gross Combination Weight Rating(GCWR)[i]=23000

With 4.10 Axle Ratio You Can Tow 15700 lbs
Gross Vehicle Weight Rating(GVWR)[i]=12200

they dont even quote specs for long bed SRW, they do however quote specs for short bed SRW and they are.....


With 3.73 Axle Ratio You Can Tow 13850 lbs
Gross Vehicle Weight Rating(GVWR)[i]=10100
Payload[i]=3120
Curb Weight[i]=6980
Curb WeightFront/Rear=4266/2714
GAWR[i]Front/Rear=5200/6200
Gross Combination Weight Rating(GCWR)[i]=21000


i guess i just find the page where the quote long bed SRW...

 

I agree with everything you just said. I misunderstood some of your earlier post. Another important factor is brakes (Truck AND Trailer) and the brake controller.
