We did Nova Scotia and New Brunswick last July. Went about 4200 miles with our v-10 van and tt. GCW was around 15,ooo lb by scales at first fill up. We averaged about 10.5 mpg when our ac didn't work and a worst of 8.5 with the a/c. Met some very nice and some not so nice where ever we went.
If you go through Truro, beware of Hollis Ford. In fixing some wiring, they broke more and it caused us to stay there 8 days instead of 3 or 4. Fortunately, we were parked at a relative's friend's house for the duration.
Overall, it was a nice trip.
