I've started building a 2-car trailer for two ITA CRX's. The trailers specs are:
- 24.0' X 6.5' deck
- tandum 3500# axles with brakes on both
- leaf spring over axle suspension
- 15" wheels with load C rated tires
- 2x4 box frame (2 on each side for car wheels)
- 2x2 cross bracing
- 1/8" plate on wheel tracks only
- tongue 2x5
- 2-5/16" 10,000# ball
- load distribution hitch
- break away kit & brake controller

I'll fill you guys in on the details, and how it hauls if your interested.
