The one Im running currently gets a bit hot on long pulls up hills when Im pulling my 24' goosneck with a large cat skidder which weighs around 11K total. Im going to be heading to northern NM for an elk hunt and Ill be towing a 9K fifth wheel and a 20' enclosed trailer with a jeep, 4wheeler and all the other supplies needed for 5 guys out in the woods for two weeks. Should I modify my current tune or does someone have a nice safe tow tune for my stockish LBZ? Im finally getting my laptop back next week so I can start learning how to do all this stuff.
