My 2001 Ford E450 knocks when under load, accelerating while towing vehicle, or going up steep hill. Had Ford mechanic check vacuum, said it's OK. Using top tier gas. It starts and runs better than any vehicle I've owned and doesn't knock when accelerating w/o the towed car on flat road. Also does 'revert to defrost' when under load; that is, AC from vent is redirected to defrost until reach crest of hill and reduce load. Help! Thanks.
