Well, it finally happened to me in Dateline Arizona. At 105 deg in the shade, I was poking around in the hydraulic valve compartment trying to find the 1/4 inch nut Chris at WRV told me would be there. Of course there was no room for hand and tool but Since Chris told me other owners had managed to loosen the pressure release solenoid, I managed to be successful.
Once Janet and I pushed the wardrobe back in, we blocked it closed with that 2x4 that everyone is supposed to have in their rig (right!) We used some rolled up air mattresses and made it back to San Diego with no further problems.
Post mortem: One hose blew at the metal fitting and the other one was severely bubbled despite the fact that the hoses had the WRV heat shields and were fastened up above the radiator.
