Thanks, La monte and Gerald.
La Monte, I don't think I will add struts under the bed because the only time I can foresee getting under there again is to manually retract or repair the slide. Our bed sits crosswise, with the closet across the rear, so it is not over the engine. If your bed is over the engine I see why you need access.
Gerald, It may be easier to repair the slide than manually retract it, if no parts are needed or if parts are locally available. I have both the electrical and mechanical capability to diagnose and repair a problem. But if parts are needed, and unavailable, I still want an alternative to make the coach drivable. Thanks for your advice. The participants on this forum are a great resource, Sam
