34TBOK Monitor Panel
We have a new 2013 Sabre 34TBOK and I have a question about the holding tank monitor panel. There are two black tanks listed and two grey yet on the outside of the trailer, there is an outlet in front of the wheels which have the handles labelled as Grey 1 and Waste Water (black) for the bathroom. Behind the wheels there is a another outlet with the handles labeled Grey 2 and Grey 3 which I think are the same tank for the indoor and outdoor kitchen sinks. What is confusing is that the Grey 1 shows up as Grey 3 on the panel and I'm pretty sure that Waste Water is Black 1. What I don't understand is what the Black 2 level indicator is for when I'm sure that there are only three tanks on this unit.
Any clarification would be great!
