and see the Tilley tilting trailer. 1. Takes an ordinary cat trailer. 2. Cut the axle and insert piece for max width. 3. Build frame which bolts on. 4. Go wherever. Been using this for 10 or so years now. If it's blowing over 20 or so crosswind, Tami strips the trampoline but even then all the thing does is fishtail some, which is hard on the tires but not really that bad.
