I have a 2012 Solera, and as already noted by others, the area in the tank flush area (black and gray water outlets) is quite narrow. I've been looking at the HydroFlush (45 and 90 degree angles) and the FlushKing, but doubt I could connect any of these in the space available. Would love to use anything which would make flushing tanks easier and more efficient. Wondering what systems or suggestions Solera owners might have??
