Turning radius I'd never considered. Strength...well, don't see how it could be any weaker than a car steering box. They're not made for large tires or abuse either. Plenty of CJ's with big tires around. Hmmmm.

I'm not trying to discount what you're saying, just sort of thinking aloud. Some additional thought will have to go into it.
