According to Dodge, the max towing capacity, if it is a long bed with a 4.10 rearend, is 10,700. If it is a 3.73 rearend it's only 8,700. If it is a short bed the weight goes up 100 pounds on each due to the lighter truck. Here is the link for future reference.

IMHO....Are they autos? You are basicly comparing apples to apples. The Dodge(349ci) has the quad cab(more weight?). The Chevy(367ci)is still basicly in the same class...I don't think either is rated to tow 10,000lbs.(not sure?) That would be my question to the dealer...the facts man! Not it will do the job. I have a 2500 dodge diesel auto and it is rated at just short of 10,000lbs. Sure you can exceded that (and I have) but if I knew I was going to pull a possible 10,000-11,000 lb trailer all the time I would be looking for a dually. More excellent opinions will follow I'm sure!

I pull my 3H CM slant with a 02 Ram 1500 with the old 5.9L V8 which the Hemi completely replaced in '03.

I would say NO to the Dodge and I am completely happy with mine.  My truck has all the power I need for my 3 horses and tack -  However, you are adding extra weight for the 3/4 ton chasis, about 800 lbs for the 4x4 option, and you are wanting to pull more weight than I do.

While I have argued that half tons are completely acceptable and capable of towing I think you have stepped over the std truck train of thought.  Consider going with a diesel and heavier tranny.

Looked it up again 11,750#s...my flatbed is rated at 10,000lbs..anyway it is a "03" std output 4x4 quad cab auto 3:73...with a chip.

If I always pulled 10,000lbs I'd still get a dually (maybe).

well that sounds a little more appropriate........as for 10000lbs just get me a stouter WDH, a ZF manual tranny and more motor for the trailblazer(hey isuzu can you fit that inline 6 diesel in my truck?) and let her rip.......maybe?

BTW anyone know anymore about the v6 diesel that was supposed to show up in the 1/2 fords?  i heard that got canceled. damn, that really had my interest.

One thing you may consider as well is a Superduty with the V10. Plenty of power and mileage is pretty good considering your in a 3/4 or 1 ton truck. Average 12-14 MPG even with your foot into it.

It's a motor that you don't see talked about much on here. It is also a proven one with very few, if any issues. Mated to a 4.10 or 4.30 rearend and you can tow right next to any diesel.

Also

Yes I do, it's a 2001 F-250 with the V-10. It's a 4x4 Crew Cab longbed. The numbers for 01-04 are 310 HP and 425 TQ.

If you keep the original size tires and don't speed on down the road you will get 12-14 MPG easily unloaded. In the mountains with that weight expect 8-10 depending on conditions and how you drive. This motor will definitely handle your needs and makes a great family vehicle as the Ford Superduty crew cab is the biggest out there. I am 6'1" and 250 and have plenty of room wether I am in the front or back.

outstanding, another happy v10 customer.  ive driven a  few v10s, liked what i saw and felt, havent towed with one, although everyone ive talked to said with the 4.30 rear it will run with the diesel..........or close enough. since im looking for a 3rd vehicle (basically tow only) mpg doesnt matter and i dont really care to pay the "diesel premium", i may step up the hunt for a 6 speed SD v10.
