it when considering just the weight limitations. Thats only 900 more pounds than what I have now. Now maybe the engineers are being conservative but I have to go by the placard. So if I load the airstream and the truck the way I want to that leaves me with only 400 lbs to the good. Not exactly the margin I was looking for . . . .

Your thoughts on the 4.10's make sense.

While the 4.10's aren't as attractive as in years past -- and so long as solo mpg is otherwise acceptable (as is increased engine wear) -- then hold out for what you want. GM gives big credence to the gear change for increased GVWR, etc., so that is a good line to follow short of reducing the load.

dnzf0g,

The Gross on the Classic 25 2006 is 8300 lbs. Its never been that heavy because
of my Tow vehicle limitations. But if I let the wife load it without supervision well!

Pappy

You might want to run it across the scales. My GVWR is 10,000, but fully loaded (ceramic dishes and a LOT of stuff, a little water in the tank) I'm at 8,500 lbs with empty weight 7260. I run with a scooter, an inflatable 11' boat, 10 hp motor, gas for boat.....

I really struggle with the thought that you'll be at 16,000lbs (or that close). Have you scaled it?

dznf0g,

I have put it on the CAT a couple of times and the way it was loaded at that time
put it at 7300 lbs. The Sierra 2500HD gas sticker weights were all around 7200 lb range that would bring it up to 14700 with out my wife and the kitchen sink. Smile
Its that Kitchen sink that will finish off the rest of the payload.

Pappy,
If you're more comfortable with the 4.10:1 axle ratio, by all means go for it! As I mentioned in my first post, the gas mileage won't be 10% lower, nor will the engine wear be 10% greater. I'm based my recommendation on the fact that with a six speed transmission, an engine with a flat/broad torque curve and the fact that the torque converter will unlock when it needs to for additional torque multiplication; the transmission control module will find a sweet gear ratio for virtually any situation.

Your thinking on GCWR has merit and you are the person who's buying the truck. I wish you many miles of trouble-free driving!

All my best,

Steve

Steve,

Thanks I am trying to get one ordered. Hate it that most of the camping weather will be gone before it gets here. It sure is nice to have a group like this to bounce
ideas off of before making these decisons.

Pappy

Pappy, Curb weight of a 2500 Sierra Denali, gas is about 6601 with AWD (plus or minus depending on options)...GVWR is 9500....that's WITH the wife, kitchen sink AND a bunch of other stuff in the bed.
If you're really putting enough in the truck to put it at GVWR (2900 lbs), then you're prolly at or around the GCWR.

I think you're over killin' it based on my experience and loading (heavy), but I'd rather see it that way than you convincing yourself to get a 1/2 ton and saying it's fully capable. I DO THINK you will see a 10% fuel penalty....I've compared them myself. But like my daddy used to say...there are some things more important than fuel mileage.

All that said, I'd get the 3.73.

I had a 2007 2500HD, 6L 4.10. Got 10 mpg with a 98 30 foot Excella and the same with my 10 , FC 25 fb. The 2500 crew had a very hard ride when not towing. Wife complained so traded. Had a 08 yukon with 5.? and 3.43 best ride but terrible towing. It had the short wheelbase. got 11 mpg towing. I now have a Dodge 5.7 and so far so good.

Pappy,

Soundz like your DW lodz like mine....

I've been loaded to 15960 combined. The max for our rig is 19000, I like the extra wiggle-room the 4:10's provide.

The new 6 speeds do close the gap though.

Still, go with whatever gives you the margins your comfortable with.

Stream Happy....

Bob

I had the '07 GM 2500 SLT 6.0L Crew Cab with the 4.10. I had an issue with the truck constantly downshifting and revving the engine up to near the redline at any hint of an incline. I couldnt get much out of the dealer to resolve the issue and ended up getting rid of the truck for an Excursion.
The GMC had plenty of power and was very comfortable. If I could have had the shifting issue addressed/ resolved, I may still have the truck.

The 6 speed cures a lot of that. I've yet to have a 6.0/3.73/6 speed shift to anything below 4th gear...but I've not been in "real" mountains with that combo either.

I have a 2011 Chevy 2500HD with the Duramax and tow a 97 34' Airstream that can gross out at 9800lbs. With 397hp and 765lbs of torque and 3.73 gear ratio, the truck doesn't know the trailer is back there. Your torque is what moves a load while horsepower is how fast you can do it. I've driven over Raton Pass in sixth gear with and cruise control set at 65 with trailer attached and the transmission never downshifted while maintaining my speed at 1650 RPM. My past truck and trailer combo was a 97 chevy 3/4 ton 454 gasser with a 4L80E transmission and 3.73 gear ratio and pulled a 94 30' airstream. The truck had 290hp and i believe 410 lbs of torque. On the same trip the truck would slow to about 45 to 50 and down shift to third and about 4000 RPM.

So in my opinion get the truck that make's the most torque and is rated for the load you are going to be pulling and you will be happy.

Hope this helps.

Can't touch high compression, but gearing makes a real difference (trans or axle).
