I have a 2004 SunVoyager Atarium model. It has electric slide out in the bedroom. The motor is under the bed. Now if this does not work I understand you must unlock the brake on the motor and use a wrench and crank it in by hand. How can you raise the bed get under it and crak it in. Does not seem possible to be since I am 80 years old. Have any of you had this problem?
