raywen, While I am no expert on weight ect I did go with the dually as I felt it would provide for more stable towing its like having an extra set of feet on the ground. Along with that we have the BNW hitch and a Glide Ride pin box that provides for a pleasent towing experience with very little surging or side to side type movement.
What year 30'RSO do you have?

What manufacturer??? Daily driver??
On Dodge at least the SRW has a slitely higher GVWR that the dually. But the dually will be more stable pulling large/heavy loads.

Pulling a 5er, a DRW will be more stable than a SRW due the extra width at the rear of the truck.

In most configurations, a DRW will have a higher GVWR and rear axle GAWR than will a SRW.

There are a lot of 5ers that can be pulled with a SRW and the pin weight will still fall within the trucks GVWR and GAWR.

For estimating purposes, the typical 5er will have a pin weight close to 20% of the trailer GVWR when loaded.

But do not go by the pay load capacity published on the truck as it is based on a base model, no cargo, no hitch, no accessories and only a 150# driver. So you will need to decrease the published payload capacity by the extra passengers, cargo, accessories and hitch.

My F350 has a GVWR of 11,500# and based on the published payload capacity, I should be able to carry a lot more than I really can. The truck scales at 8000# with full fuel, me and Ma, and the toolbox and hitch...so by rating, all I can carry is 3500#.

450Donn,

I've seen SRW trucks with higher manufacturer's trailer tow ratings than DRW trucks. This is due to the SRW being a lighter truck and sharing a GCWR with the DRW truck. However, I don't recall any SRW trucks having higher GVWRs than DRWs. Can you cite specifics?

The 2007 Dodge Ram brochure. And don't quote me on these numbers as I am not at home and the brochure is. But 6.7L/automatic/4.10 rear end ratio the towing rating for a SRW is 16,500 and the dually is 15,800. Yea, shocked me too. I would have thought my dually would have a higher rating.

TXiceman · 09-17-2007, 10:37 AM

450Donn, you are confusing towing capacity and payload capacity. A DRW will have a lower towing capacity than a SRW because the dually will weigh more with the extra wheels and fenders. This is based on the trucks GCWR (gross combined weight rating) less the weight of the truck.

With a 5er, the hitch weight is a big factor since it can be 20% (or higher) of the trailers GVWR.

A DRW will be able co carry more weight on the truck since it has a heavier axle, 4 tires in the rear and heavier springs. A SRW will tow more since it weighs less, but it can not carry as much as a DRW. With a 5er, the pin weight is close to double that of a travel trailer.

You have to read the small print and footnotes on towing a 5er.

Check out THIS site for weight info.

In a 5th wheel application, the SRW truck will typically exceed its GVWR long before the manufacturer's trailer tow rating (which is what you're quoting) is reached. In the real world, the DRW truck can handle a larger 5th wheel because of its higher GVWR/rear axle GAWR.

I think that is what I said.

The SRW, as Ken and I have noted, does not have a higher GVWR than the DRW. It has a higher manufacturer's trailer towing rating. This is a prime example of why the manufacturer's trailer towing rating is often misleading, especially in 5th wheel applications.
