x2 on the dehumidifier. I to had condensation in various areas of my 5r. Now I run my dehumidifier every time the humidity is above 70% (inside the RV) and 1) the windows have to be closed 2) winter camping, ceramic heaters, ensuring cabinets, bunk racks, bed and bath are opened until the dehumidifier shows below 40% on the LED.
To big to put on the counter for drainage so I dump mine daily. It maintains 30-35% and has an auto feature too. Love it.
