Capilano is very convenient. Although our TT is only 24ft, we had on issues whatsoever. You won't have any problems. There are larger fifth wheels there in the park.
We stayed one night and then stored the rv in front for $18 a night. They also have no service sites for $45. We took the SUV on the ferry to Naniamo and headed to Campbell River for four days.
Capilano was the best thing for a foreigner. We even drove through town across the bridge downtown and through afternoon traffic. Great way to see the sights on your way.
There is also a mall, restaurants, and shopping within walking distance of the park. We recommend the place.
