You're in a different facet of the industry. I've heard most flatbed loads don't have appointments, or they're not very strict. The machines on your trailer don't have an expiration date. My company's schedules are (supposedly) based on a 50 mph average but in real life that never happens unless you average at least 60. To average 60, unless the route is all interstate, you have to go 65 as much as possible. They don't plan for the loads being loaded late (happens about half the time) or time spent getting fuel, lunch, CAT scales, bad weather, orange barrel zones, etc. For me it's pretty much just keep the hammer down and the left door closed or you'll be late.
