Ok I'm going to be driving the AlCan Ak to Pa to Fl in mid March. I have an 02 F-250 7.3 with 155000 miles. The only thing I've done to it is change the starter. I got it with 80000 miles. I'm going to say everything is stock and has never been changed other than oils and filters. I've never had any problems other than a couple hard starting cold mornings -30 not pluged in my bad. I was wondering if I could get some recommendations on things that would be smart to change before I do this 5000+ mile drive. Thanks Bret
