Gab,
The only part of that advice I'm not sure of is the piece about having all the stuff you need for possible flats.. with those Gumballs forget about it!!! Although Justin makes a very good point... especially having AAA
So, you've got a breaker bar with that huge socket for the single wheel nut.. With all the spare wheel parts you've accumulated, have you thought about getting the wheel guys to fab you some sort of trick spare wheel on a space saver that will fit in the trunk? After all it is a street car right?
The old Ferrari 512BBs used something similar as some of them had the single splined hub.. think some of the TRs did as well. Just a thought.
+1 on enjoying the scenery!! America The Beautiful is an absolute truth!
My cross country trek didn't have the hyper energy that you guys had/will have.. but it was fun non-the less driving the flamed dually!
