Heavy towing - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just picked up a 71 Blazer. What is the factory towing capacity? I'd love to be able to pull a 10k lb. trailer/toy hauler.
Obviously an electronic brake controller, but what else would be necessary? Beefing up the frame? Heavier brakes?

Let's start with letting gravity do its job:

10k with that short wheel base and 1/2 ton brakes---not practical.

There are a few threads on the topic if you try a search. Here’s one example: http://67-72chevytrucks.com/vboard/s...d.php?t=806020

Your 2016 Silverado should handle the job well. I wouldn't recommend the Blazer for the job.

I used my Blazer to tow a car hauler with a 79 Camaro on it about 40 miles on the freeway. Once. Now my Yukon gets those jobs.

Good luck with that !!
I pull an empty 4100LB 17ft toy hauler 3 1/2 hours once a year to a car show, and it's not fun. I used to pull a 2500LB popup trailer and it was fine, but I would say that's the maximum. Even with the best brakes in the world and lots of power, the real problem is the 104" wheelbase that you can't do anything about. Someone mentioned your 2016 Silverado, but unless it's at least a 3/4 ton, it will be just as unsafe pulling 10000 lbs regardless what the dealer says it will pull.

I can't remember what I had in the car trailer, maybe the Nova & golf cart. Obviously it was loaded way nose heavy. Didn't tow it any where just moved some stuff around the property. The thread reminded me of the picture.

I think it really has to do with how you setup the Blazer. Trailer brakes and a weight distribution setup with sway control is how I run my setup. Not sure what our 21' toybox weighs but with a manx buggy, kids bikes, 140gal of water and all the other crap inside I would bet its still under 10k. As long as you keep it under 75 it doesn't talk back too much (unless I'm used to it now). I've done a number of drivetrain, brake and suspension upgrades and its been good. Still running manual steeling; probably make 5-6 trips a year. Also use it to drag a number of other fun things around. Good luck!
