Do you ever notice people drivers behind you with the windshield washers going? I leave our fresh water tank drain open and have had a few people pass me pointing to the water running out. It takes several days for it to drain at times. I have to be pin down for it to drain.What I do is leave the cap (small garden hose sized) off while driving down the road and any leftover GRAY water works it way out. BTW don't follow me too close LOL
It really doesn't matter if it is one or two. I labeled mine as Galley and Bathroom instead of 1 and 2
Hoganc,
Sorry for the delay in the response. We have been crazy getting ready for our Louisville Trade show. Lots of exiting new products for the next year. To answer you question. All bighorns have the same set up. Grey tank 1 is for the upper deck (bathroom and Shower) and Grey Tank 2 is for the kitchen.
I hope this helps.
