Welcome mijones & congrats on your new Cougar HC.
You'll enjoy towing a 5th wheel. First tip: swing wide when turning, until you learn the difference in the way it tracks behind the truck.
2nd hint: remember the height will be over 12 ft now... be aware of tree limbs/branches and building overhangs, etc, etc.
Next suggestion... Have FUN!!
