Hey folks,

Just got done with a short four day camping trip to Frances Slocum State Park in NE PA only about 60 miles from my home. The CG site only had electric hookup. I ensured my FW tank was full before leaving home.

My Laredo has 43 gallon FW tank. Unfortunately the tank sensor was dropping more quickly than I expected. We JUST made it through the four days. As my DW was JUST finishing the breakfast dishes, the pump started sucking air...water reserve empty. We conserved water as much as possible and used the CG facilities as was convenient. Just didn't seem like we went through 43 gallons.

So as soon as we got home this afternoon, I did a little experiment. I filled the FW tank until overflowing through the tank vent. Then I measured water capacity by pumping out water via the on-board pump through the TT's outdoor hose hookup and the short coiled TT stock hose. I kept filling a five gallon water tote that I know was pretty accurate.

Bottom line, after going through the experiment twice, I got 36 gallons out of the FW tank the first time, and 34 gallons the second time. But certainly fell short of the advertised 43 gallon capacity.

Any explanation/thoughts on roughly 20% shortfall in advertised FW tank capacity???

Thanks,
Mike
