Our trailer is 20' long and weighs 4200 pounds ready to camp.
We towed it with a Trailblazer LS 4.2 with the 3.42 gears for 5 years. We don’t live in a flat state, so our towing included mountain towing.
You will need to install a transmission cooler on the Trailblazer.
Do not tow in overdrive, the overdrive clutch in the transmission will not handle the load.
I had the transmission serviced every year when we were towing with it.
The Trailblazer has P rated tires with squishy sidewalls. LT tires were hard to find in the stock size. I ended up using the highest load rated P tires I could find, and inflated to maximum pressure.
Replace the shocks on the Trailblazer, the OEM ones are probably worn out, they are also valved way too soft.
Check the sway bar end links also; the OEM ones are usually worn out by 40k miles.
Keep your speed to 60 mph or less, and expect to get about 8-9 mpg towing.
The short wheelbase on the Trailblazer is the biggest problem; expect a lot of movement whenever a truck passes you.
I never did feel comfortable enough towing with the Trailblazer to let my wife drive very much while we were towing with it.
