Review: I bought this auto changeover valve to replace what I guess was the original valve on my 2005 Coachmen Capri 29FKS travel trailer. So far I am impressed with this valve. I have had one tank in primary mode and removed the secondary tank to have it refilled. My primary tank has not emptied yet so I can't yet comment on the auto changeover feature or the primary tank low pressure indicator window function. One thing I will note is that my setup is a standard two tank setup on the tongue of a travel trailer with two 30 pound propane tanks covered with a plastic weather shield. The original valve had the low primary pressure indicator on top of the valve where it was visible when the access panel was opened on top of the propane tank weather shield. This new valve does not have a top indicator. The indicator is on the face of the valve and it will take a mirror to see it properly without removing the weather shield from the tanks. I knew this from the reviews by other purchasers and also from the pictures of the product, but the price was really good compared to some other models so I figured I'd try it out. This is a relatively early review in that the valve has only been installed for about 3 weeks, but I am happy with it so far. My valve did come with a bracket attached to it with one hole at the top which slides over the center hold down rod in the tank assembly. I believe my previous, original valve had a bracket with two holes (top and bottom) but this one hole setup is working fine. I put the horizontal tank hold-down bar in place, then slide the new valve mounting bracket hole onto the rod and finally spin the hold down nut assembly on the top. I did also purchase two new pigtail hoses that connect to the tanks with acme connectors and connect to this new valve with the flare fittings. With the original valve and hoses I had smelled propane tracer in the access panel of the propane tank shield which was probably due to the original hoses failing but I figured at this price the valve replacement would be a good idea to do, too.
