My trailer is always plugged in and I leave a dehumidifier hooked up inside. Here in FL, the humidity is brutal and without it, moisture just hangs from everything.
I currently have the drain line going through the front bulkhead to the refer cabinet, and it drains out on the ground.
Even at the worst humidity here, the trailer is nice and dry inside. Hot, but dry.
Out in the woods, or in the city, It's all the same to me.
When I'm drivin' free, the world's my home....When I'm mobile.
