Holding tank capacity

My wife and I have purchased a used 1998 King of the Road (R34RK) 5th wheel. We were told that King of the Road is one of the companies who are no longer in business, so we can't contact them however we did get the owners manual and it has helped us greatly. I can"t find in the manual any information about holding tank capacity, My concern is how much fresh water do I have? Yes the gauges work but I don't know how much water I'm starting with for this boondocking trip. Can anyone help me?

One way to find out... Empty your tank. Use a stopwatch to find out how long it takes to fill a one gallon jug. Now check the time to fill your main freshwater tank. Divide one into the other and you have your answer.

Example: 0:21 sec to fill one gallon, and 20 minutes to fill tank.

Minutes X 60 = Seconds to fill Secs to fill divided by time for 1 gal = tank size.
20 X 60= 1200 1200/21=57.14

So with the example your tank would be around 57 gallons give or take.

Hope this helps.

If you can conveniently reach the tanks, use this Panner Sales Home Page
tank size calculator. Otherwise, Dave offered the only solution.

If you can measure your fresh water tank and get a cubic foot capacity then multiply times 7.5 gallons per cubic foot.

Or you could ues the 5 gallon method

Option 1: Drain tanks, close drain

Fill five gallon pail, empty into gravety fill
Re-fill Re-empty

Count the number of times you do this, Multiply by five, measure water remaining in pail when tank is full, and subtract.

Option 2; Fill dank

Drain into five gallon pail, count number of times you empty pail, multiply by five and measure amount in the final drain, add.

Example, 11 fills, 8 gallons remaining (Method one) 52 gallons

-0r- Emptied it 10 times, 2 gallons left, 52 gallons (method 2)

That' show tank capacities have been measured since some achient dude ran through the streets stark naked shouting EUREKA, EURAKA (Which means I've found it) What had he found that was so exciting.....

A way to keep his head firmly mounted on his shoulders where it belonged.

Because he'd been told a head would indeed roll (As in fact it did) his or, the thief's.. Depending on if he could prove the theft. He did, so he lived.

Home is where I park it!
