From the OP:
Do you try to find a Minyan or just daven alone?
That would depend on both the trip’s required schedule of events and the availability/closeness of a minyan. For example, if I didn’t have a rental car and the closest minyan was driving distance only, I would most likely not fool with an unfamiliar public transit system to get there.
Do you bring food or buy on the road? (even if there is no kosher restaurants you can always find plenty of Kosher food at a grocery store with the OU on it)…
I’d map the location where I was staying before leaving to gain familiarity with the local grocery stores. I would also bring supplies.
What happens if you have to go out to dinner with a client and there is no Kosher restaurants around?
I would request to have the meeting location at the hotel/office. Fortunately in my work, we don’t have business lunches/dinners like that, and if I’m invited, I can politely refuse or change the locale per my organization’s protocols, so I’ve never had to ask a shaila.
Shaking hands with the opposite sex in a business setting?
I would avoid it.
Note that these are my personal answers, not a directive for others.

Joseph:
Has maris ayin been repealed from our laws?
Why? Did you really think that I was grilling George Foreman in the grill? Would anyone think that?
It seems apparent to me from the context that Joseph was referring to entering a non-kosher restaurant, not using a portable grill to prepare kosher meat. So unless you were grilling some meat on your portable grill and then bringing it into a non-kosher restaurant to eat, I don’t think he was referring to you.
