Great time for your post. I have 8,500 lb loaded travel trailer. Box is 32 and 36 overall. Currently pulling and have been for one year now, with a 2013 Silverado 1500, with 5.3 and 6 speed. I live in Florida and 5 of our trips were in state, the other two were at stone mountain in Georgia. We are planning to buy a 1 ton this year. Was leaving only to diesel power until the last couple of weeks. I have started to think about the extra cost and whether or not I can justify it.

Right now I usually lock it in 4th manually and put it in tow haul mode. Anything steeper than a quick standard over pass and its down shifting to 3rd to hold 63-65 on cruise. Going to Georgia I spend a good amount of time in 3rd.

Seems like from reading this thread that I might be alright in a 6.0 Gasser Silverado.

What could I expect upgrading to the 6.0 in my Florida travels and the smokies that we plan to hit this fall.

Thanks

I would hold off for a couple months. I keep hearing these rumors of a HD 6.2 being offered in the HD GM trucks. This is supposedly coming for 2017. If that is true I think we should start seeing whether that is in fact what is coming soon. Normally the new model year trucks start production in July. The 6.0 is a great motor, likely one of the best gas engines built. I think the HD version of the 6.2 could be every bit as good with considerably more power than the 6.0 I would like to see a confirmation on this from GM, have not seen that yet.

Oh and I forgot to add that I have 3.42 gears.

Your header stated 3.73 gears.

But what I said still holds true. In fact the overall ratio with a 4.10 vs 3.43 will be very close as you go down in gears.

By that I mean 6th gear with a 4.10 will have a very close overall gearing as the 3.42 will have in 5th gear and so on as you go down in the gears on the 6 speed transmission.

Who is Barney? the nut on the towing side?
I lost his forum years ago for being bias.
And that's being polite.
He was a down right rude old dude who reminded me of a relative I had to see each Christmas.
Now if your talking Andy and Barney I'm good with Maybery.

There is nothing wrong with operating in third gear. That is the whole purpose of a transmission.

A 4.10 reared will not give you anymore horsepower than a 3.73.

Gears do not increase power output.

You will find with the newer 6 and 8 speed transmissions the truck will be able to pull the hills at virtually the same speed with either a 4.10 vs a 3.73.

The only difference the 3.73 may require one gear lower but that is the purpose of a transmission.

The 6 and 8 speed transmissions have gearing that will keep most gas engines in their peak horsepower rpm range.

Good gravy!!!! Someone gets it!!!!! I can't believe it!!!

Struggle? Nope I pull 10k with mine and don't have an issue. U will spend some time in 4th or even 3rd gear, but never will the truck struggle or blow apart or die along side the road... It's all about perception, I have pulled with gas and diesel and chose gas. With the 6 speed u will notice a much improvement in how the power band is used verse the older 4 speed models.

It wont be an issue. Pulled twice that at higher elevations than Yellowstone with the same setup. Gas is cheap, excepted in West Yellowstone.

When the RPMs go up, turn up the radio and just keep cruisin :)
