DW and I planned a two week stay in Montreal last fall 2016 followed by a one week stay in Quebec. We planned our stay at the Camping Alouette RV Resort (really nice place) near Montreal and to drive into the city daily to see the sights. Driving was a BIG MISTAKE!!!
We had to fight very heavy daily commuter traffic into and out of the city as well as near gridlock traffic in the city each day. In the city it was impossible to find parking anywhere near the interesting sites and most parking meters only allowed for 1 hr (or less) parking. We ended up spending more time sitting in the pickup looking for parking than actually seeing the sights. Most Montreal drivers have compact or sub-compact cars so maneuvering my MID-SIZED Canyon (like your Tacoma) was like driving a Sherman tank down a narrow alleyway. Did I mention the pothole canyon roads? As a result, we cancelled our Quebec stay.
If you really want to see Quebec and Montreal, PARK your RV in a STORAGE site at a nearby RV park, take a taxi into the city, and rent a room at one of the many tourist motels. You can then take a tour bus to the more popular sites or just walk around near the motel.
