Dualies are fuel hogs, and don't add that much to towing capacity.

Perhaps, but it seems intuitive that they would add to stability,
braking and tongue weight capability. Why else would people buy
them?

You made me get out the book. The K3500 regular cab with single rear wheels can pull a max trailer
weight of 15,400 lbs. With dual rear wheels the max weight is 16,500 lbs.

Personally, I don't think the extra 1100 lbs is worth it, but if you've got a trailer weighing that
much, then the dually becomes necessary.

For 9000 lbs, I wouldn't even think about it.

The issue is tongue weight, a dually will certainly be able to handle
more tongue weight.

That is silly. I have a 1/2 ton PU that is rated to tow slightly over
10,000 lbs. That is a Class V hitch, which has a tongue weight limit
of 1,200#. 9,000 lbs exceeds the capability of a Class IV hitch.

I have a diesel dually that will pull 21,700, but now were talking a
2,600# tongue weight, which isn't practical to hang aft of the rear
wheels. So, go with the fifth wheel. Consider that this takes oversize
gears, adequate transmission, and heavy duty cooling.

I've got Kevin filtered, so didn't see his post. Tongue weight for the 2500HD or 3500HD should be
10-15% of the trailer weight. The increase in max weight for the dually is about 1100 lbs. That
would mean max tongue weight for a dually would increase by about 110-165.lbs.

That's it. What kind of diesel dually do you have that will take a 2600# tongue weight? The most I
can see for a 3500HD, diesel or not, is 1500 lbs, and that's with a weight distributing hitch.
