I have weight distribution and installed a bigger transmission cooler would that help
We towed our 21 foot hybrid with our 2003 Trailblazer for 5 years. Our Trailblazer has a 5000 pound towing limit.
Our trailer has a brochure weight of 2886 pounds, the brochure weight does not include any options like A/C propane tanks or battery. Ready to camp our trailer is 4300 pounds.
I installed an extra transmission cooler, and had the transmission serviced every year when we were towing. At that time there were no LT tires in the odd size this platform uses, so I went with the highest load rated P series tires I could get. I also installed heavy duty shocks on the rear.
I was NEVER comfortable towing the trailer with the Trailblazer. The vehicle is too narrow and the wheelbase is too short, anything passing you will cause excessive movement, read SWAY. I only got 7-8 MPG towing, the small tank means frequent fuel stops.
I would say get a larger tow vehicle. But if you decide to do it anyway NEVER tow in overdrive. The OD clutch in the transmission will fail. There are no towing mirrors for the GM 360, we were using the universal strap on mirrors.
