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.

I think he's talking about a 9,000 lb boat plus fuel, water, supplies
and trailer weight. I'd guess something more like 13,000 or 14,000
lbs going down the road.

You'd think, and all of that extra rubber on the road has got to make
a contribution to stabilty and braking. You've also got the safety
issue with redundant rear tires. If it was me, I'd get a crew cab
dualie.

6400 dry maybe 9000 or a bit more with 100 gal fuel and 40 water, plus
a few heavy items like the generator and air conditioner. It has
trailer lights built into the back of the boat and is only 8 1/2 feet
wide.

I'm thinking the extra rubber adds to the breaking, but that it's included in the calculations of
max towing capacity.

The frame of the truck remains the same. The tongue weight should be 10-15% of the trailer weight up
to a max, for the 2500HD or 3500HD, of 750 lbs. With a weight distributing hitch, that goes up 1500
lbs. The book makes no distinction for hitch weight changes with regard to duallys.

For fifth wheel trailers, the kingpin weight should be 15-25% of the trailer weight, up to the max
trailer weight as I mentioned earlier (15,400 or 16,500).

All of this is for a 2009 model Silverado.

-------------------------------------------

Probably not much difference in tongue weight. But more stability as they
have a wider footprint. Probably not much difference in fuel mileage, but
for that size boat, if not in berth, I would find storage near the ramp and
only tow it a short distance. Sort of like they do in Hawaii.

As I said earlier, max tongue weight is dependant on max trailer weight and type hitch used. There
is no distinction for tire configuration except for the max trailer weight difference of about 1100
lbs.

Tires also have a load rating. The more tires contacting the ground, the
more weight you have.

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.
