Picked up our 171 yesterday, and overall things went fairly smoothly for the first trip with it. 77 miles home to the storage center averaging 10.4 mpg over hilly terrain and wind in my face, so I'm okay with that. Haven't towed anything in almost 30 years now, so it seemed like forever for me to actually pull out of the dealer and onto the highway that they are on ... am pretty sure I heard them snickering from inside.
But, better safe than sorry. Felt good after about 10 miles in and relaxed some, and when we pulled off for lunch and into a shopping center there were no pangs of anxiety. Stopped by home first so that Comet could take a sniff around inside, and then over to where we are storing it. Only took us 20 minutes to get it settled in for a couple weeks stay (including pulling the battery and locking it away inside so it isn't as easy to steal) so not bad for our first time ... wife was very impressed with how quickly it went.
Couple of pics from the day -- first is at the dealer with our 171 and TV. Don't know why the back door is open. Second is Comet seeming to enjoy his first chance at checking out the bed!
