Beware of this scam while on the road

When you think it can't happen to you, it can. I was in GA, Exit 2, I-75. Went in to pay for gas and dh was in motorhome. A man comes up to him and says "sir, when you pulled in, I saw steam coming out from under your motorhome when you went through that water puddle.. you have a problem and my friend and I can help you out." Now, my late husband was about 95 at the time and I was the driver. I watched the gauges all the way I-75 from near Tampa. No problems... Guy repeated the story to me and said pop the hood... well, I did.. and he turns the fan, said "there is your problem, the fan motor is bad." I can fix it for $200 and will need to go get the part." Can you spell last of our $200? bye bye...? I told him, since I had nothing on gauges indicating a problem, and I had 30 miles to my first stop, I would drive on. Thanked him and left. Wow. Hubby would have fallen in for it immediately. Me? No. Got to cg and told mgr story.. he checked the fan and said that is the way it is supposed to be. But, if I wanted, there was a Ford company in town and on my way out in the morning, have it checked for our peace of mind. I did and it was all good. Scam, scam, scam.

Now that I am on the road alone, Ranger (dog) Ruger and I are more cautious.
