Question Holding tank size

[Russellvh]

I realize everyone and every RV is different but wondering. If I plan to boondock and sometimes 5 - 7 days is there a “rule” how big my tanks need to be? Two adults and very new to trailer camping.

There’s no rule because everyone lives differently. It really depends on how you plan to live while boondocking.

You could try a dry run while you
full hookups. Just turn off city water and operate like you’re boondocking, see how long you last.

Two of us get along fine with 60 gallons for 6 days. We conserve and only take 'navy' showers.

Even with full hock up, we still bring along a couple gallons of water from home. Having that for coffee and regular drinking saves some from the holding tank capacity.
