I am embarking on a DIY camper trailer build. I have done 2 skoolies in the past, but never something from the frame, up. Looking to do about a 16'. My tow vehicle is limited to 3500#. The reason for building my own is I have a brother in a wheelchair, and there's just nothing out there suitable. I thought of converting a toy hauler, but they are pricey. So...I start today by putting the hitch on the van. Monday, I have 800# of steel coming to weld up the frame. My reason for being here is to get tips and tricks along the way for strong but lightweight superstructure and furnishings.
