I don't think the rear suspension from the LNT8000 snowplow wouldn't be strong enough for the mixer from the PayStar. Check with Daniel from Plaskit. He has a Neway air suspension & the L & LTS hoods.
Should be an intersting build. I agree with Robert; you're going to need to use the L hood instead of the LN hood. What rear suspension are you going to use?
It might be a Fiat, but maybe it will have better brakes than Chrysler. Maybe it's just living here in the Northeast, but Chrysler brakes just don't seem to last very long.
