Thank you all for your responses. I will look into the issues mentioned and will let you know the outcome! Happy travels!

So sorry to hear of this invasion. I have being a victim. I believe you are more computer literate than most. Good for you! Can you state the insurance company that is giving you a hard time? At least their initials.

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.
