Never camped with our trailer but may do so a few times this year and in preparing for that I have been filling the forum with questions :)

To this point we have taken our trailer to many day shows and very much appreciate the toliet and AC (or heat).  We have a 32 gallon fresh water tank and even with alot of people using the toliet I would guess we use very little water although I have never checked...always just fill before we go.

As we begin to consider a day or two with no water hookups I am wondering how much planning I should do....I am a planner not a roll the dice type.  If there is two of us taking two showers each, shutting off the water while we soap, etc. should 32 gallons of water go a long way?  Would it be overkill to take the shower and run it into a 1 gallon bucket and time it?  In other words know that we use 1 gallon a minute and keep track of the water we are using?
