Where can one learn about the dump trucking business?

Best way to be to talk to a fleet owner who is into what you're into - there's going to be a difference between dump trucking for road construction, dump trucking for a coal mine, dump trucking for landscape materials delivery, etc. If you'd like, I have experience in several dump truck jobs and also as a small fleet owner of tractor-trailer end dumps, and you can email me at the address listed on my profile page with any questions you might have in regards to this.
