If your battery is draining in two hours you have a seriously major drain on your battery or your battery is bad. You shouldn't have to pull all these extra fuses to preserve battery life while flat towing. It also sounds like your charge line might be hooked up incorrectly or is just bad. I recommend replacing it with the BrakeBuddy Towed Vehicle Battery Charge Kit Item # BB54FR. You should not remove fuse # 16 as your brakes could lock up while towing and cause an accident. The owner's manual states to remove fuse # 32 while flat towing to prevent the battery from draining.
If after all this you're still having issues with the battery draining please reply back and we can look into another solution.
