This has got to be a fraud.  Area code for AZ, way too cheap trailer in TN.

 Listing #161903

Looks like a real deal! ... I would call him, if I wanted a "Sundowner" valulite in TN.  (Remember all the rust problems lol)  

He might have a cell phone with a service contracted in AZ.  My daughter has a cell phone with service in WV.   

Ask if it's been wrecked or damaged.   There's no pics of the interior or floor.  This may be a deal for someone... that's been educated on what to look for in horse trailer condition, on this forum

Go into this with full allert on, but there are deals to be had out there.

So... who is going to take him up on his offer?

An AZ area code doesn't necessarilly mean a fraud.  When we moved to NM we kept our TX cell phone numbers since our kids already knew them and I wanted to make sure they could call if they got lost or in trouble.  We don't have a house phone, no sense in paying for both.

A lot of people were suspicious when I was selling my gelding so I got my daughter a prepaid virgin mobile phone with a NM number and changed the ad to that number instead.  That's all a smart thief would have to do.  The prepaid companies don't know where you really live.
