I like the convenience of the automatic switch... If you get one and it is mounted in the cabinet inside the coach, you may want to look into one that uses DC powered relays... From what I'd read, the AC powered ones can hum, which would be annoying if you have it in the living area (vs in the "basement" like they are on a lot of SOBs....)

For what it's worth, my coach came with the Parallax switch.. It did not hum and seemed well made, but the switching was always somewhat noisy, and in the end, one of the relays froze up and I had to replace it as Parallax said they would not do repairs on out of warranty switches. I ended up going with the below switch... While the cabinet on it is plastic instead of metal like the Parallax, the switches are dead quiet even when they are switching over from one source to another... And the plastic cabinet is adequate on my installation as again, it is inside the coach in a cabinet...

I'd originally planned to replace my Parallax with a more expensive switch, but the seller ended up being out of the model I'd chosen, and he called me up and pitched me on the Boondocker and I took a chance... Seller said he'd stand behind it if I was not happy... So far it's been great. No regrets and the money saved is always a good thing...
