Winter RVing in Southern B.C.

WE spent part of last winter in White Rock, then left for CA. Never too cold but rainy. We had bought a catalytic heater for warmth to avoid furnace noise but found it generated much moisture despite good ventilation. There was no good complaining. We're both Scots so know what to expect on a west coast. WE can recommend the rv campground at the truck crossing, not cheap but well run.
