Since we shoot for 1/3 full on the FWT, I have the DW watch the gauge inside... pushing it every few seconds until 1/3 shows.
Not exactly this subject, but closely related...
From the posts here, seems like you will be dry camping and need a full FWT. We do not; however, I like to keep about 1/3 of a tank in case the bathroom is needed on the road.
If we rarely use it, is once or twice a year drain, sanitize (with rest of system), refill the FWT to 1/3 often enough... or should that water in the FWT be drained more often... since when used it pushes that stale water in the rest of the system?
This spring, I started draining and re-filling (to 1/3 tank) about every other month... am I wasting my time?
