Wife and I have been talking about how great the shower faucet is since I installed it just prior to our trip to AK that we're on now. It is especially great for boondocking because there's no fiddling with the separate hot/cold knobs. Set the temp once and leave it, then just use the on/off dial to control water flow. We have only adjusted temp a couple of times on this trip to make the shower a bit warmer as it got colder out, and a bit colder when it got hotter out. We've never had a thermostatic faucet so we're pretty surprised by just how great it works. Below is the one I bought. It was a direct replacement for the OEM faucet, with the exception that I added a backing plate to make it stick out 1/2" otherwise the wall depth is just a hair short. I know I got the idea from a thread on this forum but now I cannot recall where that was. Just thought I'd share. If you boondock much, you want this type of faucet, trust me.
