I'm no longer with Roehl but I just wanted to say that getting faster at securing and tarping loads only comes with experience. If you try to rush it when you're just starting out you're going to get yourself and quite possibly someone else hurt or killed. Flatbedding is no joke and there's no room to take short cuts. Just take your time and make sure the load is going to stay on the deck. You'll have to figure out what works for you on your own. All us flatbedders have different ways of doing things.
That being said, when I was with Roehl up until May of this year, I hauled a lot of CAT loads out of Sanford, NC. The loads always picked up at the Keen terminal next door. I could count on one hand the number of times I went south of North Carolina in 2 years with Roehl. Roehl was a good company during most of my time there and I think you're making a good choice if you decide that's where you want to work. There are better options out there though if you'd have more interest in staying in the southern states. Me being from Ohio I prefer staying down south.
