I'm not sure about the inverters, sorry. I didn't have one, and I guess I didn't pay attention to that in orientation.
ops: Of course, orientation was a long time ago, too, and maybe I just forgot what they said. Anyways, I wanted to mention a couple more things. They get a lot of oversized loads. Some guys are intimidated by oversize. Not me; I loved them. It pays extra on top of your base cpm, and it just feels cool to be set apart from all the other loads that any "old joe" can pull. But it requires paying special attention to your traveling restrictions, and some guys just don't like that. I don't think Maverick gets much oversize, I think TMC gets some oversize, and I know Hunt definately gets plenty of oversize. Also, the safety department is a stickler about logbooks. That doesn't mean you have to be paranoid about running 100% legal all of the time, but just make sure there are no silly/stupid mistakes adding up in your logbook, or they WILL crack down on you. I rarely ran 100% legal, but I made sure my logbook was meticulous and perfect, and nobody ever even blinked an eye at it. Not even Mr. DOT suspected anything during my inspections. Mr. South Dakota DOT even gave me compliments on how nice and neat my book was, even though the page he was looking at was a total lie. 8) Anyways, good luck on your decision - each one of the companies you have listed have their pro's and con's. I hope you figure out which one is best for you.
