Bryan, in regards to false economy, I don't think that this is a false economy situation. I think it is a reality of cutting expenses.
I average 700 miles a week, pretty easy to do around here, Diesel is approx $4.40 a gallon. At 8 miles to the gallon I am using 87.5 gallons of fuel a week which equals 385.00 or $1668.00 per month. It was tolerable a year ago when the fuel was around 3.00 or so a gallon.
The new truck will get around 15 miles to the gallon or 46 gallons a week. With gas a little cheaper then diesel at an avg of 3.89 right now it will reduce the fuel cost to 179.00 a week or 775.00 a month.
The new truck will cost around 350.00 a month depreciated over five years. So far it is a 600 a month savings. If I am not driving the "rolling gang box" it is not costing me other then insurance which is minimal compare to the savings I have calculated.
