    I'd say you got plugged up vents or bad crossover valve. But I gotta ask where do you live that you just leave it running all weekend? Can't you just plug it in where you park at?

    I'd check vent tube. Mine was clogged and led to that tank being pressurized and pulling out of the opposite tank.
