One other consideration when taking the ferry. They require RV's/trailers to
turn off their propane , and therefore fridge during the crossing. The shorter
6 hour crossing wasn't a problem for us, however the 16 to 18 hour crossing could be. One may need to have freeze packs in the fridge to help keep food cold. The drive across Newfoundland is about 500 miles. We chose to cross over at Port Aux Basque, then drive to and return from St. John's and return on the shorter Port Aux Basque ferry. The ferrys are quite large but we were concerned about getting sea sick on the 16-18 hour ferry. We did this last month, 48 foot total lenght RV with Smart Car & 2 persons was aprox. $380 each way.
