Congrats!!
PP is a Great ride!
I did it several years ago (once on a C-10, and once in a Model T Ford)...
(When I did it, it was gravel roads on the upper sections. Is it all blacktop now?)
If I get a chance, I may do it again someday! (C-14 or Model T)
PS: Try Mt Evans. It is a bit higher than PP....
Ride safe, Ted
