THERES not a landy in the world will go fast enough to lift a bonnet wiv a spare wheel on it!!!!.Ive been driving mine since 1974 wheel on bonnet ,iv lowered it down gently to do somthing later,forgot about gone to work then realised 3 days later oops the bonnets open,you usually remember when going over rough ground and it starts knocking,dont lose no sleep over it mate.....mind you, no wheel on make sure its locked if you dont want a face full of bonnet and loose teeth.....dave
