Being in the pump business I should have known it wasn’t the pump.
So if you are having slide issues here’s here’s the simple way to test them. The fitting sizes are a 1/4 JIC. Get two 1/4 jic caps then you can isolate the bedroom slides from the lower slides. You can then see if the slides work. My bedroom would only go out a foot or so, but when I isolated the bedroom slide and ran the lower slides they worked fine.
I also got two test port fittings (1/4 jic )and gauges.
Hope we learned something from this. I think I’ll keep my Montana for a couple more years.
