Not wanting to hi-jack the "Halfway home" thread I thought that it'd be better to make some comments in a new thread.
I can understand the desire to immediately head back to the US where most items are cheaper. However with the Canadian buck at 90 cents US there's not all that much difference now. That being said, within days of picking ours up we'll be down at Camping World in Burlington stocking up on trailer related items.
As to having to leave Mr. Ruger in WA while you pop up to Canada, that cuts both ways. Your gun laws, as liberal as they are, still mostly prohibit a non-resident alien, that's me, a Canadian, from possessing firearms in the US.
As for "what's to see in the Vancouver area?" many books could be written. The panorama from two of the mountains minutes away are spectacular. From Mt. Baker in WA in the East to the US San Juans and Vancouver Island in the West. One of the fantastic things about living in Vancouver is the proximity to a vast array of differing scenery. You can be boating or kayaking in the morning, hiking in a canyon in the afternoon or cycling around Stanley Park and skiing at night, never more than a half hour from home. Disclaimer: no I don't work for the tourism board but I've traveled enough to know a good thing when I see it.
The only negative I see, and this doesn't just relate to Vancouver, is that it's sometimes difficult to find a place to park the trailer near the city so that you can go do tourist stuff without it. In my case, if I saw someone posting "do you know any place close to Vancouver that we could park overnight?" I'd probably answer "my driveway".
