During the past year with my new fifth wheel when unhooking I always pulled the pin and dropped the front feet and then raised the trailer with the extend button. A couple of times I had difficulty manually lifting one of the feet up to store after hooked up. Thank goodness I ran into the right mechanic. He told me when unhooking to always electrically extend the feet 3" first AND THEN pull the pin to drop the feet. Since following this procedure I have never had the problem again. Has anyone heard this before. Hope this makes sense and will help someone out.
