WE did the trip up from Baie Commeau up to Lab City then across the trans Lab highway to Happy Valley/Goose Bay, then we took the ferry down the coast and then docked in Newfoundland.
We did it in the summer with a 5th wheel RV way back in 1993, it was about 2 years after the highway opened. It was pit run gravel back then but we had no issues other than getting a tankful of winter diesel in Goose Bay, the truck didn't like it.
The trip down the coast was great, the ferry had lots of space for the truck/trailer combo, from memory it was about 30 hours and we had a cabin.
These days it might be like the Alaska Highway where you can almost rest your full coffee cup on the dash without spilling it compared to the older times!
