Earlier this Summer, I purchased a 2010 Keystone Montana 3400RL and noticed that the landing gear raised and lowered very, very slowly and with hardly any sound at all. Then, after a couple of trips, no movement, no sound. Checked battery - good. Checked power to landing gear motor - good.
Decided motor was dead. Turned off battery. Cut the red/black wires to the motor. Used socket ratchet to remove 4 bolts that hold motor to wall and ordered through nearby dealer: Stromberg Carlson Landing Gear Motor LG-142178. Fit perfectly. Reconnected wires.
Works great!
