Will give my .02 also.
I have a 3/4 ton Chevy extended cab, so I have no problems pulling my 25' cruise light.
The reason i have the 3/4 ton is my 1/2 ton scared me to death about 3 times and the 4th time, I got a 3/4 ton.
GET the factory integrated brake controller, INSIST on it, you will never be happier.
As others stated, get the towing package also. On the Chevy's that normally includes the extra tranny cooler.
NEVER try to pull it when not in tow/haul mode. On the Chevy's that will have it stay in the lower gear longer (less gas milage) but will keep the tranny temps down.
