I had an El Cheapo 3000 pound winch on my car hauler for more than a year.
It worked fine on a single line pull.
Using a double line pull, I dragged an 85 GMC 2500 4X4 onto the trailer.
It had been sitting on four flat 12.00 tires for 7 years, and the bed was full of construction scraps, including the Western plow. I had to stop a few times, and cool the motor, but it did the job.
I was amazed.
RARGREEN is still using this winch.
