In 2008 we made the trip up the west coast of Newfoundland arriving in Port aux Basque, traveled up the west coast crossed Labrador and came down Route 389 crossing at Bae Comeau.
For us it was a two month trip. We're relatively slow travelers and at the time the road Trans Labrador Highway was not paved. Before we left we read all numerous trip reports from others. WE also requested a list of all gas stations on the TLH from the tourist bureau. They provided an east to west list with the gas stations listed in order providing the station and home phone numbers of the owners.
We towed a 16 foot trailer with our Honda CRV, it had a 15 gallon tank. Our rule was to stop at virtually every gas station, there were not that many but enough. Never got close to a fuel issue. WE did carry a generator
and had a gallon or so tank for it. We always carry a spare fan belt, tire repair kit, a real spare, a bottle jack and a compressor.
It took us two months, it may take you longer if you plan to do justice to the west coast of Newfoundland. For example it's easy to lose yourself in Gros Morne. (Part of the reason for two months for us was the unpaved road was a slow drive for us.)
I will say you will miss out on the icebergs, an amazing feature of a Newfoundland trip and a reason we always go early in the spring.
I will email you a list of west coast highlights.
I often here people took about insects in NL. WE never see any, maybe because we travel in early spring.
I will dig out notes from our trips and send you a west coast trip plan. FOr us the west coast is a month.
I should have it to you via email this week. Generally these things are too long for PMs.
Of course I'm jealous, missing are almost annual trip this year.
