2017 REDWOOD 39MB, Have issue with slide retracting after it has been exsteaded for awhile,
have to literally push on it to help it in, readjusted slide arms to what appeared to be the original location from washer rust mark's, have actually bought a pair of screw jack to support to remove some of the extended weight of slide, anybody else been down this road

Yes, we have experienced some of the same issues with our 17 MB. Take a look at my post (subject Wiper Seal) under General Exterior; I believe I’m the second post. Since having the seals replaced and the slide realigned it is better but that slide is still somewhat stubborn to close; we’ve been able to close it by rocking the switch back and forth a few times and it finally will close. A couple days ago while checking the batteries I discovered loose crimps on both the power and ground leads running to the hydraulic pump ( as well as some other loose crimps and wires), they were loose enough to wiggle around by hand. This makes me think that the pump is not getting enough power. I don’t have a crimp tool but have quite a bit of experience soldering so I’m thinking of soldering all the connections. I’ll let you know when I get this done and if it helps. I’d suggest checking out all the 12v connections, especially at the ground points.
