The original poster wrote that he has a long slide out that extends two to three feet. That is a very heavy slide out compared to ours, which is also long, but only about 18" deep. I can understand the difficulty keeping the motors in sync. if they are stopped part way to drain water off the top.
We have water getting into the RV at times when we retract the slide out. Next time we are out and it is raining, will attempt to level the RV with the slide side slightly lower that the other side, in hopes that the water will run away from the RV. I have never used the levelers manually, but I will need to learn how.
