no plans to start work on this for some time, but the more I design it

You're going to _build_ a road grader? =:-O
I'd suggest going to someplace that has them or uses them, and ask some
questions and look at one. For some reason, I got a mental picture of one
where the front wheel strut has a sort of a "roll" pivot, so that the front
wheels could be on one slope, and the back wheels would be at the other.

But what do I know? ;-)

Let us know how it comes out, OK?
