Teardrops n Tiny Travel Trailers

I want a very cheap old tent trailer ($0-300ish) for my tear drop build. Mostly just for the frame and axle but if anything else such as a stove, dinette, roof vents, etc are salvageable that is a bonus. Condition mostly does not matter, must be towable even if I have to change the wheels on site.

I live in the Edmonton, AB, Canada area and am willing to drive up to 300km or some for the right unit.
