Hello all. Sorry in advance for a newbie question. I have an 86 diesel (M1009) blazer, and I'd like to set it up to do some towing. Nothing too major - I figured a little trailer for odds and ends / dump runs, and a travel trailer of 25 feet or shorter. I know this means I'm looking at a hitch mounted to the frame, but I don't know much else. Can anyone out there help clue me in? Is this a bad idea to begin with? Do I need a transmission cooler? Thanks!
