2026 3100RL fresh tank capacity and roof bubbles

[A&D Bond]

We just purchased in May and love the new design. We are full timers in the RV and plan on traveling outside of WA when retirement hits in a couple years.

A couple things I have noticed, is that the fresh says it is a 77-gallon tank, yet I can only put in 55 gallons of water. We just noticed bubbles on the roof and hope that repair goes smoothly.

Some have speculated that the “calculated” fresh water volume may include water in the pipes + the water heater.

I read that too, we have a thankless water heater and I honestly don't believe that the lines hold 22 gallons.

I would try a different flow meter.
