When looking at the chevy's keep your eyes out for a Z71 (if you're looking for 4wd). They typically have the towing package with a hitch, 7 pin connector, and trans cooler. I'll also agree that the prodigy brake controller is the way to go. If you're not comfortable installing it yourself than I wouldn't think it would cost much to have a mechanic put it in, it takes less than an hour for joe homeowner to do one. Do your homework, look at the durability and typicall life of the 5.3 offered in the chevys. There are many, many 5.3 litre trucks running around with 200K+ on them. Tells me GM got something right.
