So we're coming from Bend, OR, to Flagstaff, AZ, got gas in Stockton (from 70F to 105F!) and heard a whump sound. The living room slide crept out about an inch or two and a red puddle formed under the slide. RV was bleeding!
We had the slide secured inside with the OEM slide latches, so it couldn't come out any further than that, ran the pump to try to bring it all the way back in and a spray of fluid came out under the slide. We managed to make reservations at a nearby resort so I could investigate further.
Our RV (1997 Rexhall Rexair) has a 200-series HWH leveling system with kick-down jacks, and a living room slide-out. The slide-out is the type that has 2 through-chassis rams and a sensing valve instead of a equalization cylinder. It has storage doors under the slide that can be opened to see the sensing valve and hoses, and I noticed that of the two hoses that go from the manifold to the slide, one of the hoses had a cracked outer shell, the other one was also in bad shape. But those aren't what burst. One of the two lines that go from the sensing valve to the front ram burst.
The rams are inside of housings, there's a pivot bracket on the driver side end, and the other end of the rams is accessible from the passenger-side storage bay. It looks like the extend-retract lines go through a hole in each ram housing.
So here's my real problem:
I was able to find an HWH manual for Winnebago that seems to closely or exactly match my system. In the manual, it seems to indicate that the slide be extended to remove and replace the ram, which seems necessary in order to disconnect and replace the hoses. When I try to extend the jacks (required to operate the slide-out), fluid sprays from the burst hose. The schematics in the manual support this, because pressure is applied through the T fittings under the slide when the pump runs. I don't seem to be able to extend the jacks to support the RV when the slide is extended, and I don't know if the slide can even BE extended with the burst hose.
We're headed to Williams, AZ, I can work on it there and probably get new hoses from Carquest in Flagstaff, but I need to solve this problem before I can get the hoses replaced. I can sort of reach everything from under the RV to disconnect the ram hoses from the sensing valve, and if the rams can be removed through the passenger-side end of the ram housings with the room retracted, it seems like the rest would just be making sure I cap the hose ends and keep everything in the same position when I remove the rams and put them back in. Has anyone done this before? Thanks for any help that can be provided.
