Bill Ward has made a very cool compact caravan. It’s based on a Shasta Teardrop Travel Trailer. While the doors are a little hard to find I suspect most of us could whip up a little variant of this to show off in a display.
EDIT We liked this one so much that Andrew blogged it too:
Details like the vent on the roof and Bill’s choice of the old-style door are excellent. The trailer is being pulled by the SUV from 7635 4WD with Horse Trailer.
