Ridgeline awesome truck, but?
I owned a Ridgey this summer. It was so first rate in every way. Absolutely the best lighter duty truck there ever has been and maybe my favorite truck ever. I had to sell it once I got into camping and got a 29' Ambassador as the Ridge couldn't pull it. We bought another trailer which was a 2004 24' Keystone. The Ridge would have pulled it just fine. Now, we are in a 2004 25' International. I bet the Ridge could pull it, but I have a first-rate rig in a new 2007 5.7 liter Tundra. It's overkill for our Airstream and tows it like a dream.
I think a 22' Airstream would pair well with a Ridge.
It's not where you are, but your reason for being there.
