If you check their websites,
Scamp and
Casita might have a referral program where owners agree to show their trailers, and find units in your area to see. I know
Escape trailers does this -- I own one, and have shown it multiple times.
Escape makes a 17',and you may be able to find a used one of those. BTW,
Escape isn't that far from you; they're in Chilliwack, BC.
