I may be married to my current truck. But a divorce or separation in immanant. Its just a matter of funds and timing.
I'll replace the money I've spent on this truck. Its paid for itself many times over and it will continue to serve me well until I am ready.
My only issue is old iron and worry about what I got myself into.. or new-ish to go after the fuel mileage. In my opinion its only a matter of time before we see $4 - $5 gal fuel. When that time comes.. that 379 may look nice but I'd rather be yanking at 7 - 8 mpg vs 5 - 6 mpg.
I'm really leaning hard on the 579. I saw one the other day. Black, long wheel base, no farings, polished tanks, polished stacks, sounded good. Almost thought it could have been a TMC truck..some guy out of Tn. That would be a keeper for me.
