2005 envoy

We have a 2004 Buick Rainier sister with 5.3 and 3.73's, which is rated to tow 6500. No way would I want to tow that much or length of the trailer you noted. The 360 wheel base is to short. It does turn on a dime and give 9 cents change. Chris

Had a 2003 Envoy pulling a 16' Haulmark enclosed with 1 Harley and 2 ATV's. Weight was right at 5,800# by scale. Trans went out at 35,000 while towing through the Smokey's. GM replaced it under warranty. Drove it for another 5 years pulling the trailer many times through mountains. Gave it to our grandson with 148,000 miles. He still drives it, somewhere over the 200k mark now.

As a former Envoy owner towing a 21' hybrid TT, the Envoy wouldn't be up to the task. The soft suspension and 4-speed 4L60E transmission are big drawbacks. You see the replacement tow vehicle in my sig.

First things first, welcome! Lots of knowledge here and lots of helpful folks.

You'll have no issues with power and general ability to tow.

To ChooChooMan's point, you have other limitations. I had an '03 Trailblazer. I believe the hitch is rated for 950# with a WD hitch. What concerns me is your payload. Look at the yellow weight sticker in your driver side door jamb. It will list your payload. It might be 1200# or 1300#. That sounds good until you subtract the tongue weight and the weight of the WDH, likely you're looking at close to 900#, which gets subtracted from the payload. Now you have 300# left for your spouse, kids, dog, and "stuff". You can see that you'll most likely exceed your payload rating.

Moreover, that trailer is a bit large for a GMT360 platform. I had an EXT (GMT370) and I would not have towed anything longer than 20/21 foot. If you have the SWB, that KZ is too much trailer for that truck.

I would say no way. Looks like an Envoy 4WD has a "tow rating" of 5700lbs and 2wd has 5900lbs. Your trailer will probably weigh about 6000 to 6500lbs ready to camp. That weight will also include 650 to 900lbs of tongue weight. Your hitch may not be rated for it, and with passengers and gear in the vehicle, you will probably exceed the vehicle's gross weight rating and possibly the axle rating.
