I have a 94 xlt with the factory cooler/ warmer and I have a hitch I just put on. I'm getting ready to buy a house and I'm looking at getting a 5x8 or 5x10 steel utility trailer to use around the house. I'm not pulling anything heavy with it. It's mainly for a couple of sheets of drywall or plywood or boards and whatnot. I was going to put a auxiliary cooling on the truck but I don't think I'm going to. What are your opinions on it? Should I get one or will I be fine with a 5x8 trailer that I use every now and then. My truck has 160xxx miles on it and I think the trans was rebuilt before I bought it not too long ago.
