David,
Since the 3000 is not available with dual wheels I would have serious doubts about using it on slopes of 30-40 degrees. You MIGHT be able to go straight up and down, but not turn on the slopes or drive across the face of sideslopes. You can certainly question your Ventrac dealer on this, but I think it highly unlikely that a 3000 would work.
Have you actually measured your slopes with a carpenters protractor level?
