Unit is a 2001 National Caribbean Diesel. Step cover slide motor just hums when switched to "on"
I cannot find a way to access this motor without taking drastic measures such as cutting a hole in the floor. I also had the unit at a respected RV Repair place --- he spent about 1 hour trying to access with no luck.
Please help. Does anyone know of a club or association of former National Employees ???
Any input will be appreciated.Thanks in advance.
