Remember, T. mentioned that this is his first tour. Once he gets into the rhythm and has a few weeks under his belt, he'll be more confident taking "roads less traveled".
Also, by following the AC routes, he'll have a greater chance of meeting other bicyclists for camaraderie and support.
In any case, going through the Mohave, Death Valley or Arizona desert in June is not going to be easy, even for the experienced cyclist. If he has more of a survival/challenge mindset, then great...but it's not my idea of fun.
