Starting Point recommendations Bunk House 5er MFG and Models

Outdoor kitchen is nice if it has a sink and mini frig. Will help reduce trips into the trailer to washup. The frig only runs on shore power, if you put cold drinks in it when you get there it should catch up quickly.
Another nice option to consider would be a half bath in the bunk area with an outside door going into the bath. Again limiting the foot traffic through the trailer.
