A Half ton is not going to like 6000 pounds just saying.
I pulled our camper 7 hours last weekend. 6400 dry, probably close to 7 loaded. Tahoe didn't bat an eye at it. We towed the ozark area, which is far from flat ground towing.

@MSDENEEN , if it has a trans collier stock, it'll be mounted in between the grill piece and the radiator. Like at @Red Rocket said, the factory one is pretty small. I upgraded mine to the tricolor 40k unit and it's awesome. Check out the first page of my build thread for a couple photos of the cooler.
Were did you find the tricolor trans cooler i did a search and nothing comes up???
