IronMike,
Welcome to the "block". We're sure you'll find the neighborhood a very helpful place. We've found the folks here very supportive and experienced.
We just started towing a larger (26 ft) Airstream with the
1500 V8 and you should have no problem. For what it's worth, if it's a new one with the rotating dial transmission selector, I've read of people reaching up and turning off their radio, then exiting the truck with it still in drive.
Good luck and many enjoyable adventures,
Roy and Marie
