I've been slowly rebuilding the interior of my 2001 EB50 SMB. Currently designing new cabinets for the back, which enclose the furnace and hot water heater. I'm using Autodesk Fusion 360 to model. The included McMaster-Carr add-in allows searching for and inserting 80/20 part models. The rest I modeled myself in the app.
Modeling this had really helped with all the dimensions. None of which in the van seem easy to figure out since nothing seems aligned or straight
The image is of the current stage of the design. I've left out the left side storage as well as some other parts. Still adding items as needed to flesh out the design.
Thought folks might be interested in seeing what's possible with tools like this.
