To remove motor:
Support the awning tube with a step ladder,, After disconecting motor assembly from awning arm (Multiple ways to do that) and unplugging motor from harness drill out the 3 pop rivets, Pull straight out of tube.
in 2006 those motors were $400 dollars each.
How do I know this? Thankfully by observation, Had to help a fellow camper, His motor was under warranty, Did the emergency roll up as per owner's manual,, Called Rachel (RV service Technician) She told me the price.
Home is where I park it!
