Just found out about the independent front suspension used in some Freightliner RV chassis.
Here is a link to some info, in this link is another link to a PDF brochure with some good pictures of it.

The front suspension is made by, or designed by, ZF, here is a link to some info from them.

It looks like a regular A arm coil spring suspension, but bigger and with air springs.
Also uses 17" air disc brakes.
Available in 12,000 lb or 14,000 lb capacity.
10 lug wheels (semi truck size).
Hydraulic assist rack and pinion steering.
And perhaps the best part, 60 degree steering angle, (read really really tight turning radius)

I have not seen one in person yet, but will be looking for one to inspect.
Also don't know the track width, and the frame rail spacing, but theoretically it could be used under about a 3 ton truck with a little narrowing of the front cross member, think about making a modern Cannonball (big AD GMC COE)...
The rear suspension on the same chassis are also air ride, and could be more simply swapped to something older.

Just ideas, as I don't need another truck or project for a long time.
Anyone else think I am crazy?
