{"replyTo":"","text":"I'll ask a logical question.  What's the point in paying 20-30k more for a long hood truck that makes you less money?  The operating costs, fuel burn, is about half what an aero truck might achieve.  You are operating a business, for profit, but choose equipment that costs more to purchase and significantly more to operate due to its fuel burn.  All bc it looks good?  You spend all that time out there away from your family to make significantly less money just to have a long hood?  Do the math on what you spend to fuel for a year at 4/5 mpg and what you'd have at 7/8.","replyToPid":0}

","text":"I'm sorry driver. I do not know anything about you.  You also do not know me. I have never been in a junk volvo or company truck.  \nI am glad you bought what you wanted. Next time I would suggest asking other o/o spec questions. (not the dealer) That way you get a truck speced for looks, and mpg, etc... Just my opinion. \nI didn't mean to be rude.","replyToPid":476733}
