I know a guy who put in over $30,000 into a 2004 T800 in 2013. Its a spare truck so doesn't see a lot of work but it was what was required to keep it on the road for the next few years. Older trucks suffer from fatigue especially when you got it for $9000 to me it says there will be bills in the future because the guy you bought it off of didn't fix it up before he sold it. Don't remove driver pay from the equation unless you don't plan on paying yourself. Its always a cost whether you are a O/O or a company driver.
Well essentially drivers pay becomes what's left over at the end of the day. I can't assume .40 a mile when it's not there.
