I used some steel U channel down the center for the tail wheel to sit on and made some ramps for the wheels to go up on. The plane trailers backwards sitting down on the tail and the main gear. A typical boat type of winch pulls the plane up on the trailer and also holds the tail in place when on the trailer. Tire chains designed for automobiles to use in the snow turnbuckle over the main wheels to keep them in place.
The trailer had to be made significantly longer, but I did this with 4 inch and 3-1/2 inch Square beams telescoping longer when the plane is on the trailer, and telescoping to a nice short tidy size when the plane is not being trailered.
Go to a boating store and look at several models. I am sure you will see a way to easily modify one for your use. You can usually find somebody willing to sell one cheap. Mine had a carrying rating of 1500 lb, so it should work well with me not in it and a minimum amount of fuel.
