I bought my 2021 Silverado 2500 LTZ on April 1, 2021, while it was “in-transit”. I bought the 100,000-mile warranty just to deal with electronic failures. I have 5 trailers that I tow regularly ranging from a small 2 place utility to my 35 foot TT (8,500 lbs). I am coming out of a 2012 Ford Raptor with the 6.2 V8. I had plenty of power to tow all my trailers, but the TT was sometimes a handful. The Raptor had 35” tires on 17” wheels so a lot of sidewall movement when towing in the wind or passing a semi. The new 2500 is rock solid when towing the TT and it holds 10th gear almost all the time. I am getting excellent non-towing mileage. My best 25-mile=30.3, 50-mile=28.3, 400=21.1. When I hand calculate the tank, I usually get 17-19 if not towing anything and depending upon how many city miles I put on it. It is very rarely driven less than 90 miles per drive. Towing is ok: My 7’ tall 23’ long enclosed trailer=12.1, my TT = 10.2. Those are both 20% increase over the Raptor. I run Optilube XDP in every tank. My regens happen at 805 (+-5) miles and the soot is usually 50-70%. I get around 600-1000 miles/gal of DEF depending on towing or not. I drive like the old man I am, usually between 68-70 on the highway and 60 on country roads. Speed is the enemy of these trucks when it comes to MPG.

My first toy was a CTS3 for monitoring the truck. My second purchase was Diode Dynamics Pro SAE yellow fog lights. I am looking at the upfitter switch install so I can get my train horns on the 2500.

Compared to the some of the horror stories I have read on the forum concerning mileage and DEF usage I am very happy with the truck.

Happy to hear a positve experience with a new truck. So much of what is posted are problems. And rightly so, I suppose, since that's a primary purpose of an owners forum. That mileage is fantastic. I saw 19 mpg once, maybe, I think:unsure:. Mines an LML and my foot may be heavier than yours🚀

Awesome truck! We hope you're loving our SS3 fog light kit!

Are you towing anything heavy or just your TT?

So it sounds like, all-in, it’s costing you quite a bit more to tow with this truck than it cost with the Raptor.
8,500 lbs is way to heavy to pull with a Raptor. I was in the RV business. 8,500 lb travel trailer is too heavy for any 1500. An 8,500 load on a flatbed trailer, ok, but a travel trailer, especially bumper pull requires a little more weight in the tow vehicle.

Agreed. That is why I went up to the 2500. The problem is I am in between, light for a 2500 6.6 Duramax but heavy for a 1500, especially in any kind of cross wind. I probably should have got the 2500 6.6 gasser. The Raptor pulled it great, even held 6th most of the time (6 speed) but the suspension was not up to the task.

Yes it is typically not the power of the tow vehicle that is the problem, but the weight of the vehicle. RV’s have the tendency to push around the tow vehicle if it isn’t sized right. I noticed a huge difference even going from a short bed to a long bed. The extra wheelbase helped keep things straight during cross winds.

Either way, I would rather be oversized than undersized. Your setup is great. As for the gas vs diesel. I tried an HD gas. It is really not ideal for RV towing because of how often you have to stop for gas. I had about a 200 mile range with my 2020 Ram HD gas, and about 400 miles with my diesel. When out west, 200 miles isn’t quite enough range to feel safe, for me.

No, the TT is the heaviest trailer I tow. I am only getting 10mpg while towing. That tells me is is working pretty good to move it along. Even my enclosed is only getting 12 and it is making regular trips up north hunting or snowmobiling. My EGTs seem to stay "warm" and on some trips my soot level is less than when I started.

I do question the finances of buying the 2500 Diesel. The maintenance is certainly more $$$. The other reason for the 2500 is a planned month long RV trip out west through the mountains. The Raptor was going to need some body work and shock rebuilds. Also, I am done playing in the sand as Silver Lake.

I never understand, nor can I follow the logic of these statements. A new 1/2 ton is rated to tow over 13,000 pounds, but people say it’s unsafe to tow at 2/3 of the maximum rated towing capacity. Why? You say it’s because the truck doesn’t weigh enough. Well, everything scales. A 8,500 pound camper will have less surface area than a 13,000+ pound FW, so the wind factor idea doesn’t really apply. The new half tons weigh as much as the old 3/4/1-ton trucks, and people had no problem towing well over 8,500 pounds with those trucks. And finally, for the ”truck doesn’t weigh enough” argument, look at which new truck is rated to tow the most weight, a RC, 2WD truck, the lightest truck of them all. yet that truck is rated to tow over 36,000 pounds. That argument doesn’t hold water.

Let‘s look at it from a different viewpoint. You say it’s unsafe to tow a trailer that is 1.5 times the weight of a half ton. By that logic, a one ton truck would be unsafe towing less than 13,000 pounds, that’s all just based off of the weight of the truck.

Or, let’s look at it from the tow ratings perspective. You say 2/3 of tow rating for half ton is unsafe, then, following that logic, towing with a one ton SRW gas truck, it would be unsafe to tow 9,600 pounds, since that is 2/3 of the weight rating for a conventional bumper pull trailer for that truck.

None of that is logical.

I have some more happy news.
I am the one that just spent 15000 on a 2012 LML LTZ duramax which included blown head gasket repair CP3 conversion and multitude of other things .
My miles per gallon went from my best tank previously which was 15 miles per gallon empty to 21 miles per gallon or almost 40% increase in fuel economy.

Towing miles per gallon went from 10 and a 1/2 to 13 or almost a 30% increased

All hand calculated 3 times to be sure and the needle on the gas gage moves noticeably slower.

And no power sacrificed.

It doesn’t need to make sense to you now, but when you do it, and have a little more experience I’m sure it will make sense.

Those 1/2 tons aren’t rated to tow 13,000 lb campers. Frontal area matters.

Owners manuals mention frontal area, and how it limits tow capacity.

I have towed over 50 different campers with 8 different trucks. And sold 30-35 campers to people, probably showing each of them on average to 3 people. So, short story long, I’ve talked to a lot of people who tow campers. A LOT of people thought like you, because they didn’t have the experience, that if the camper was within the ‘tow rating’ it was ok. They found out that wasn’t true. Every camper I’ve bought was from auctions, I’ve bought campers that rolled on their sides and others sustained other damages. Most of them due to towing with inadequate tow vehicles.
By no means am I trying to convince you. I hope one day you tow a 8,500 lb camper with a 1500. You’ll learn first hand.
