For some people, getting the cheapest price on everything is their joie de vie. They would be proud to have this truck in their driveway, showing to the neighbors how "smart" they are in getting a lower price.
Unfortunately, it's not possible to tell who does good work by just looking at the truck. I used to think so, but have been proven wrong too many times to count. Have seen guys with nice, new, big trucks do crappy work, be flakey, and are arrogant to top it off. Then there are those who do beautiful work, are dependable and reasonable and nice. Yet you wonder how their truck even made it to the job, or how they even find anything in it!
Of course, I'm not just talkin' trees here.
