Terry,my daughter, and her Husband, John, are redoing a "TearDrop". Doing a mighty good job I must say.
It was a 8'x4' on a tongue-and-grove flooring on a pine chassis. He used a chevy front axle with 28" wheels. Then raised up the rear for cooking. It slept 2 only.
There is more info at http://www.tinytear.cc/history/history.gif.
We made it to the Fort Sage OHV area near Doyle. At least we made it that far. Next stop I hope will be Bend.
