Full Time RVers using mail forwarding and Denied Credit

Think it depends on the bank. When I recently bought a truck, I was financed through one bank but one of the other banks that the dealer shopped for me sent a letter telling me they denied a loan because they "couldn't verify my address". It's one of the big mail forwarding services many fulltimers use. So one bank had no problem with it and another did.

Shop around and find one that gets it and wants your business. They're out there.
