Welcome to maverick. I hope you're going to be as pleased with the company as I have been in all my years here. They might not be perfect, but they're the best I have found.
(Nobody has answered this part of your question yet) Now thats a loaded question! LOL. What exactly do you mean by "dock?" If you mean just back it up into a door/dock, well that depends on where you are loading/unloading at. You will have to back that spread axle- loaded with a 48K lb coil center loaded trailer into some of the most unbelievable places you can imagine. This is where van guys may not realize just how incredibly tricky it can be backing a loaded spread into the places we go. You will pull into a consignee sometimes and just shake your head like "really?? you want me to get it in THERE??" LOL. We get these trailers into some of the craziest places you can possibly imagine in order to load or unload. Alot of the older steel mills you may load at were built a long time ago, and the trucks and trailers have changed a bit since then! AK Steel in Butler, PA comes to mind instantly. Just take it slow. Move a few feet, stop, look, move slow, stop, correct if needed, move slow, ect., you get the point. Just look at it as a challenge, then master it.
HAHAHAHAHA! This is so true, and so applicable to a few people I've seen. One guy had a 350 mile run and went 500 miles out of the way to visit his girlfriend... That didn't go over too well. Also, for the love of everything Holy, please learn your state abbreviations. MS is Mississippi, NOT Missouri... One poor driver found that out the hard way, and he's not here anymore.
