I did run by the trailer after work just to look at it and see what all the hoopla is about.

Damned... since I only turn on one tank at a time that thingy is totally useless to me.. how much is it worth?

It is worth not having to get up at 2:00 am, on a cold, windy, raining night to turn on the other tank.
That convenience is worth me taking a peek at the regulator at regular intervals to see when the primary tank is empty. The regulator is located on the passenger side of the 5er, same as the entry door. Javi you don't know what you are missing.
