I had put my camper up as well and the stories I got were unbelievable.
One really came to mind when the caller said he was in the military and stationed in England. He would send a friend to pick it up with a cashiers check for him so he could use it to live in when he rotated home.
As soon as I asked him for his unit's deployed Autovon phone number to call to verify his deployed status, he hung up and never called back.
The crooks are out there; be careful.
