New to this. In Payson AZ area many mountain trails require vehicle to straddle V shaped, washed out, so only tires on each side make contact. Does anyone know if this is safe or not. Will Rhino 450 handle this?  

should be fine just take it easy.  if you are new to this be very careful.  straddle the ruts, and watch ahead for ruts thats shift to the left and right.  it's no fun if you are deAd.
