Thank you all! Nice tips for all of you, hadn't thought about the power steering issue. I've driven an old rack-and-pinion Toyota, but that was years ago. Didn't bother me much back then, but I'd probably appreciate the extra oomph now. (And John - I read your blog... what an interesting trip! I always wanted to tour Alaska. Don't know many people who've had the chance to stand on the Arctic Ocean.)
I'm assuming driving (and parking) an 18 footer would be a bit easier than the 22 foot models. My plan at this point is just do the test drive - adjust the mirrors (both kinds!), get onto some city streets, and then do a stretch on the highway at 60mph, get a feel for things.
Also was going to mention - originally, we had planned to get a VW Westy, so "upgrading" to an 18ft. RV seems like total luxury. Also, we want the 18 footer because we plan on doing some more "urban" legs on our road trips. Stopping in Denver or Boulder, for example... parking, doing some shopping, seeing the sites.
Thanks again... great forum, makes me feel more confident in making the Toy home plunge.
