We have a 1984 Columbia and I can safely say it's pretty much my favorite thing. This tiny camper has been so much fun. One thing I have not seen much of here as far as modifications go is replacing the axle for bigger tires. We did that a few years ago and I cannot tell you how much of a difference it has made. No more blowing tiny tires!! Easier trailering behind SUV, too. Replaced stabilizer legs in the back with longer versions and moved the shorter ones to the front. Love it.
