Don't look at what people have towed, why not research the vehicle and learn what it's designed and intended to tow. I'm sure if you look hard enough e.g. Avalanche owner's forums, you'll find people that have done incredible things like tow a 12000 lb. travel trailer sea to shining sea.....doesn't mean it's right.

An Avy is a 1/2 ton and IMHO, is maxed out at 7000 lbs., maybe even less. More than that, and the tongue weight is pushing the RAWR and GVWR of the AVY.

2010 Trailer Guide states that the Avy could tow 8,100.00 with a 3.42:1 ratio?


Posted By: skipnchar on 09/15/10 11:06am

Older ones (2007)rated to tow around 7,000 lb. but that's with a 3.42 gear and the newer ones come only with a 3.08 which is a STRICTLY economy gear so don't know what the newer tow rating might be. Don't forget to subtract the weight of any passengers, cargo or optional equipment from that tow rating to get the ACTUAL maximum tow rating. Good luck / Skip

We used to tow a 30 foot Jayco Eagle with an 03 Avalanche and it was NOT a fun experience. Looking back the trailer was probably just too heavy, also experienced lots of sway even with anti-sway control.

IMHO, they are too short wheel-based and suspension is set up soft like their SUV Tahoe/Yukon sisters to tow anything big. I am sure there are many that do big with them, but I would stick with something around 6,000 lbs max and 27 feet length max.

Our 26ft Thor Aerolite was about 5000 lbs and for my money, it was too much trailer for our '03 Avalanche 1500, 3.73 gears. A jillion rpms up any kind of grade and 7.5 mpg. Went for a larger TT and a 2500 Dodge QC CTD auto. Did nicely. JMHO

how can you find out which rear end is on the avalanche?


Posted By: T&A on 09/15/10 04:10pm

I used to pull a 28' Pioneer TT with an Avalanche 2500, 8.1 liter, 4.10 rear end, 4wd. It pulled beautifully. Got about 9 to 9.5 mpg when towing. Unfortunately, it was my daily driver and only gave me 12mph when not towing. DW also refused to pull a trailer. Now we have a MH and she still won't drive, but she is happy and I'm still RV'ing so I'm happy.

Where do you get your information?

According to Chevrolet's 2011 Online Order / Reference Guide, the "newer" Avalanche is available with either 3.08 or 3.42 ratio and has a "Maximum Trailer Weight" up to 8100#.

While 6k lbs max might be pretty close depending on loading and payload, they really don't have that short of a wheelbase. It is the same as a Suburban. I would expect they would tow as well as any Suburban if equipped the same. 1/2 ton compared to 1/2 ton or 3/4 ton compared to 3/4 ton. It all depends on your expectations, some people wouln't be happy towing a pop up with less than a 3/4 ton and if the extra stability is worth it to them then I'm ok with that. Some people drive 3/4 ton diesels and never tow anything, to each his own. Most people wouldn't use a 3/4 ton to tow my trailer but I'll probably buy a 3/4 ton Suburban in a few years. We hope to do some longer trips in the future and I want as stable as tow vehicle as possible.

well, i have a '07 Avalanche with the 5.3 v-8, 3.73 rear end and factory tow package.
the towing max is 7200lbs.

i tow a HTT that weighs a little over 5000lbs. loaded.
since i live in NorCal and have to often climb over the Sierras, the Cascades or the Siskiyous, i wouldn't want to tow much more, even though i have about a ton more towing capacity.
plus our Coast Range is taller than most "mountains" in the East.

i think it's a great tow vehicle for a 25' or smaller trailer. plus it's the "Swiss Army Knife of Trucks"!

I am happy with the way mine tows. My TT weighs around 5600# loaded and I have dragged it up and down mountains. Stay within all weight ratings and it should work fine. Use tow haul mode, keep it in 3rd to lock out OD. The steepest grades will require 2nd gear and high RPMs but the truck does not mind.

Good luck,

As you can see in my signature I pull with a 2005 Avalanche towing a #5000 TT.

I live Minnesota a pretty much a flat state except in the river valleys.

I have pulled this trailer to western Colorado Thru the Rockies and East to Washington, DC with a MPG average of just over 10 MPG, and yes I track every Gallon of fuel when pulling.

The TV handle this TT very well, no sway. I do agree with other posters that when they say when pulling a mountain pass it will run high RPM's in second gear - so what, it's not near red-line and you don't run there all day. It takes power to pull a mountain grade and the most horse power is in the higher rpm's.

I have pulled this trailer with a Chevy Trailblazer - Terrible.

I have also pulled it with a friend Dodge Turbo Diesel 3/4 ton. A great experience no sway and power to burn, however the MPG was not all that much better.

All in all, We love our Avalanche,

Happy Camping

I pull a 5K hybrid with my 1500 5.3 3.73 Z71 Avalanche through the mountains of WV/VA and do so very comfortably.I also have 2 kayaks on the roof and 5 passengers.

Stay within spec and you'll be fine.
The 5.3 is a proven engine and does'nt mind RPM's.

OH...the Avalanche is the sharpest looking 1/2 ton on the road.

Shouldn't make any difference, assuming they are equipped the same. The Avalanche is identical to the Suburban, it just has the rear roof cut off, and a cargo bed instead if a third row of seats. Mechanically, they are interchangeable.

I have an 03 1500 Avy, 4x4 w/ Z71 & 5.3l engine. I had 3.73 gears and upgraded to 4.11. I pull a 28 ft 7200k TT, (fully loaded), w/ an equalizer hitch. I live in MN and just pulled our TT to Yellowstone and back this summer. I use Tow/Haul in 3rd gear and at 65mph I run just a tad bit over 3k. I realize I am basically right at my max capacity and have made several trips to the scales to make sure I am OK. Bottom line I have never had sway issues even in MT driving in 35 mph crosswinds w/ oncoming traffic. Swat IMHO is driven more by proper hitch set up and loading of the trailer, than the vehicle. The Avy has plenty of length for most TT's. I do wish I had more power, but even pulling the mountains into Yellowstone, if I took it easy I made all the hills with out trouble. I does depend on where you live and where you plan to drive. Most of my camping is with in 1-2 hours and on flat ground, no real trouble here. Now if I lived in or near the mountains I would get a 3/4 ton something. At the end of the day the Avy is a unique vehicle design that is as capable as any 1/2 ton SUV, just be careful what you ask a 1/2 ton SUV to do. Enjoy your RV travels!!

this is true with the 2007 and on. not sure about older Avys and Burbs.

It's also true for the earlier models. From 2002 (the first year for the Av) through 2006, they are all based on the GMT800 platform. In 2007 they went through a major redesign and started calling it the GMT900 platform, but the differences are still minor. Throughout the years, the differences between the same model year Av and 'burb are mostly cosmetic: some different sheet metal and some changes to the electrical systems, but the frame, suspension, and drive-train are the same. From year to year, the individual models have changed somewhat, but the same type of changes were made simultaneously to both the Av and 'burb.

We have a 2007 Avalanche, 5.3, 3.42 and it tows my 3500 # boat like a dream. I know thats not much weight but I am also towing it over mountain passes in Colorado. I wouldn't hesitate to put 6000 #'s behind it.


Posted By: Tystevens on 09/29/10 10:29am

We towed the TT in my sig w/ the '05 'Burb, which is mechanically identical to an Avy of similar years. It did ok, depending on where you're going and how far you want to tow.

Lots of work going up mountains, struggled to maintain 60 mph on flat ground in 4th gear. Mostly had to keep in in 3rd, and it became tiresome running at 2700 rpms for 2000 mile trips. Got 8-9.5 mpg. Easy to overload if you fill up the TV and the TT's tanks -- we were always right at or slightly over the GVWR for the truck.

So the 1/2 ton didn't work great for our uses, which is why we upgraded to the 2500 Duramax. If we did shorter trips, or towed and left the TT for a while, it would be adequate.

We use a 2005 Avalanche 2500 with the 8.1 gas engine and 3.73's. It works fine with a 9000# travel trailer. I get 14 mpg empty and 8-9 mpg loaded. Very strong towing rig......
