So, this is my first attempt at building a camper. My thanks for answers and inspiration from the magnificent build by GCecchetto. I have started with my floor pack. Using 3/4" Maple ply that has been biscuit joined at all joints, and I have some TotalBoat penetrating epoxy ready to go on as soon as the weather improves here in NorCal. I was pretty amazed to find that the measurement at the top was spot on with my bottom measurement, not even 1/16th off! First time using a biscuit joiner as well, how is it I never used one of these amazing things! Anyhow heres some pics of the start and I will update when I can seal this thing and start the aluminum fabrication and welding process.
