Thanks F1 and company--love the shared knowledge here.

I've had one nose cone bolt and one front handle/top bolt fail, and carry all spares. Just back from Utah, and I'm again amazed and dismayed at some of our roads in the U.S. The road-bridge-road junction must be very hard to engineer--ugh.

Anyone successfully upgrade the Cobra suspension to help with the sharp jar and also big dips? I run 13" trailer tires at high psi, original steel rims. Does Cobra offer a heavy duty option for insert-state-here?

Thanks in advance.
