Towing with a Chevy Avalanche 1500 4x2 - Need some advice

I am new to RVing and am planning on doing some towing with a travel trailer. I need some advice from all of those towing gurus out there... I have spend what seems like and endless amount of time searching for some assurance that I am in the good.

I have a 2003 Avalanche 1500 4x2 with a 3.73 axle and locking diff. I hope to be pulling a travel trailer weighing 4900lbs dry (2004 R-Vision TB27DS). I expect the gross to be around 5500 - 6000 lbs as I don't think I will be carrying around a lot of water or heavy items. Just household stuff and some propane (FYI, the trailer's GVWR is 7693 lbs - well below what I intending on carrying). I will have about 500 lbs worth of flesh (people) in the tow vehicle and maybe an extra 200 lbs worth of stuff in the bed. The trailer's tongue weight is 690 lbs (vehicle is rated to handle 1000 lbs) and I will always be using a properly configured weight distribution hitch with some sway control and obviously trailer brakes.

Is this a sound setup for a well serviced half ton with 150K miles on it? The towing cap is 7200 lbs for my vehicle (with two people in the cab), but I doubt that is realistic (most people agree this is stretching it a bit). Would you recommend air bags? Maybe an aux tranny cooler? I have another vehicle that would handle this, but we really enjoy traveling in our Avalanche!

Remember that the Avalanche is not a truck chassis. It is an SUV with a truck bed. The same chassis as the Suburban. But it is heavy and has a nice 5.3 V8 in it.

Moderate hills here in GA. I will not be traveling at altitude or over any mountain passes... but I am a bit paranoid. I think it stems from the fact that I blew out my dad's transmission when I was 18 and dumb, pulling a trailer full of rocks... could have invested that $3,000...

Thanks! Sol

  • LouLou your limit is 8000 lbs. Per the Chevy site.
  • I am confused now, LOL it doesn't make sense some days!

    Our avalanche is classed as a truck. It is insured as a truck not an SUV. When we go to get service they say it is basically a chevy truck (sierra)with a different dressing. I guess I should question the dealer, LOL....I feel more like myself in a truck.

    Anyway....we enjoy towing with the Avalanche. If the weights work out for you then I am sure you will enjoy pulling with it.

    No. 7000-8000 pounds is about right. 12000 pounds may be the GCWR with 3.08 axle. Avalanche is based on the Suburban, not Sierra. They are fairly difference frames, chassis. And the 2003 has a 4-spd trans which makes a big difference is towing performance compared to today's 6-spds.

    Payload is the problem for the half ton Suburban and Avalanche. shaffersh1 should weigh it first, subtract from GVWR. Then take off the estimated 700 pounds of people and cargo. The rest can be used for trailer TW.

    5k dry seems like a good fit. If your truck did not have the HD towing package, then a larger trans cooler is a good idea. Use a WDH with integrated sway control, use Tow/haul mode, lock out overdrive, enjoy.
  • We have a 2012 Avalanche 5.3. 4x4 and pull basically the same trailer. 27ft 2011 Monaco light weight. The gvwr on trailer is just over 6000 lb. Towing capacity of Avalanche around 12000 lbs.

    The avalanche is the exact chassis as a chevy sierra, it is the same as a truck according to GM and the ministry of transport and plated so. We have a towing pkg on the Avalanche.

    We also pull behind the trailer our boat.

    As far as your gvwr is concerned dont go by what you think will be the weight after you are loaded. If you are stopped you will be rated on the vehicle (trailer) sticker weight.

    Our Avalanche pulls the trailer and boat with no problem. The dealer suggested the red head hitch with equalizer bars and 2 sway bars.
