If your asking me . I stay away from both if at all possible. I don't go anywhere near ports . Thank god !!!!
Step decks are usually heavier. Dundalk takes some getting used to but I don't mind it now. Actually prefer it. First time I was there I think I waited 3 hrs for someone to load me LOL.
I hate Baltimore for one , and I am about as fond of jersey as I am Baltimore. Lol I pull reefer so I really have no point in being in any ports , but hell I guess if the money is good I would pull a container. Lol, kinda like a lot lizard . I would pull anything for the right amount t of money.
No money in containers for time and hassle involved. Most flat loads will fit on a step, but not the other way around. If going into ports, you will need a $132.50 TWIC card or pay for an escort which usually start @$50 per hour.
