You will be cheating yourself if you only have 2 weeks free in Newfoundland. My wife and I did 3 weeks and only saw the western half with a one day fast trip to Gander. If possible plan to enter and leave on the 2 different ferries because there is only one road across and no reason to dead head back. Make sure you have a reservation for each.
Musts are Gross Morne National Park and Gander airport museum. Gross Morne is one of only 3 places on earth that you can walk on the mantel of the earth and the letters written by those that were put down at Gander during 9/11 are very inspiring.
We only plugged in at a private campground twice to charge our batteries and used Provincial Parks the rest of the time.
Labrador is only a short hop via ferry. While there are parks there they are very rustic and the spaces too small for most trailers. The many attraction for us was a trip out to Battle Harbor, a restored cod fishing village off shore on a small island.
I have not found or more friendly group of people anywhere than the Newfees. The ag inspector, at Port Au Pass, gave my wife her 10 year anniversary inspector pin for our brag board because she had to take our USA potatoes. Prince Edward has convinced the Canadian Government that they are the only place on earth that should grow potatoes.
