So summer 2012, I plan on driving from Pennsylvania to Prudhoe Bay, Alaska. Yes that is correct. Deadhorse, AK to the Prudhoe Bay oil fields. The vehicle I plan to use is a Ford F150. The journey is roughly 9000-10000 for a roundtrip. I will hopefully average 20mpg with this truck and if fuel is roughly $3.50 per gallon then gas would be maybe $2000. For know I am wondering what modifications I need to do to my truck in order have it ready for this journey of epic proportions. Take in mind once I get into Canada and Alaska and past Fairbanks north I'll be on the Dalton highway where the road conditions aren't exactly good. Advice?
