Dan,
As soon as you screw in the adapter it releases in the inner valve and it drains. The benefit I guess is that the valve can't accidently be opened by a rock or anything else. I was just curious if you had compared them before buying yours. They are $50 on amazon, a little steep, in my opinion.
Thanks for your thread, I enjoy it.
Thanks Jalexi! A lot of my thread is "small potatoes" jobs I enjoy and having something to post about. Not like a lot of guys here that do serious or creative work.
Speaking of non-serious, non-creative work:
We just got home from 15 day trip through the Southwest. The interstate is BAAD due to potholes. Serious ones with deep chunks of pavement missing. I straddled the truck ruts with limited success. One place there was the remnants of a chain saw in the lane I couldn't avoid because of a semi so I went over. It hit and I pulled over to inspect for pan damage. None but I could see where it had hit a frame cross member.
Laughin, NV & Gallup, NM to Taos, NM was the first leg to an intended stop - I don't like driving the RV more than about 4 hours. Afterall, the E350 chassis dates from the 80's so not all that comfortable. A lot of heat comes from the engine cover. My SO has lower back issues and since the engine cover doesn't allow her to extend her legs straight forward she's hurting after awhile.
Taos to Santa Fe, NM which I liked a LOT better than Taos. The RV park we chose from the internet was a dump but the area around the Plaza was very nice and enjoyable. Spent a day in a spa here that was bourgeois as hell but still very enjoyable.
Santa Fe to Albuquerque to meet up with sister & brother-in-law who joined us for most of rest of trip but stayed in hotels. We then drove to Canyon de Chelly (pronounced "Shay") to tour the canyon and see the cliff dwellings and ancient markings. Absolutely beeoootiful in the canyon. The area outside the canyon, a town named Chinle on the Navajo reservation is small, remote as hell and very poor. Very glad we took the tour now. We were in a cut down Chevy Tahoe with a custom roll cage. Drove much of it IN the wash which is running high from snow run off. Guide said it is usually nearly dry this time of year.
After this to Sedona, AZ - Very picturesque and also very touristy but since we hadn't been in many years we enjoyed it. Did a lot of shopping, art galleries, etc.
From there the rest was heading home. Dropped the sister & BIL in Phoenix at Sky Harbor airport. Drove from there to Blythe - EEK! Apologies to anyone here who likes Blythe but I find it depressing other than being on the river. Our dogs liked it though. A one night stay and home to Glendora Friday arriving early evening.
