Here’s an image that will make you scratch your head in confusion. This person purchased an RV for cheap some of the door and a large chunk of the side panel were missing. Most of us would scoff at such a ridiculous RV on Craigslist, but this person saw an opportunity to put their engineering (or carpentry) skills to good use.
Instead of flushing a million dollars down the drain to replace the door and side panel, this person purchased two wooden doors and hung them up on the side of the RV. We wonder whether this is even legal to ride on public roads, but that’s not a problem for engineers to worry about.
