This is my first WanderYacht, based on a 8'Lx 5'W x 5'H cargo trailer. Lots of space inside for storage and dining and cooking and sleeping- I like to be inside if the weather is bad, this works. Also used Dometic awning style windows and roof vent for all-weather operation, as they tilt out from top, + they have built in shades and screens. Simple electrical system, with a small AGM battery and charger, with LED lights and 12V power outlets. Kinda minimalistic, simple, but elegant, I think
