AZ
FYI if you are going the I-10 route to AZ then on I-17 north, from Phoenix to the Grand Canyon, the hill on I-17 between Phoenix and Flagstaff is steep and long. It will really test the meddle of your 109. If you wanted to avoid it get on I-40 and take that west to AZ to avoid that ridiculously steep hill on 17.
If you're running a dizzy with points taking along a spare set of points and a condenser wouldn't be a bad idea.
Cheers and Happy Travels!
