160 mile per day! Maybe you should be looking for an airplane instead of a high mileage vehicle! Have you looked into Rideshare?
Anyway, I'm selling my Overland too...possibly today as a matter of fact. I found that when I took off the Volant CAI system, the ported throttle body, and the Hemifever tune, that the sound isn't much louder than stock, and all that's left is a good quality stainless steel exhaust system that may contribute to improved gas mileage, which was at the least, selling feature, even if I cannot get my cost back.
Anyway...Good luck in the new job! It's always an interesting time.
