Hello forum, I'm shopping for a small 5th wheel, 4 season RV. The Escape 5.0 would be perfect for me if it was 4 season capable. I'm curious if anyone has built an enclosure for these tanks to protect from freezing? I'm aware that Escape offers a tank heater option for these models, but that requires shore power or generator power. Most 4 season RVs have enclosed waste water tanks with furnace heat plumbed into the cavity, which doesn't require shore/generator power. thanks
