I drove my box up the Alakscan highway, pulling a trailor from southeast texas to Elmendorf AFB. No problems and made 36 MPH along the way!!!! The roads here are better in town than on base, but a set of good studs, which i got, makes for the best, when ive have had alot of freinds cars get stuck, mine made it. I had to replace the batt, i replaced it with a 850CCA batt. Come on up man!!!!! wiould be cool to meet ya!!!! and join the AK scion club, Short Bus 8 (pretty cool guy!!) posted a pic of my xB above, the AK scion club one.
