Is there an easy way to align the front of the camper?

That approach is functionally identical to the laser system imo. It basically creates a visible plane that you can make sure your bed is aligned with. The laser uses a light line and 3 points. This system uses a hanging chain and 2 extra points as well as a line down the center of the bed. I already have the parts to try the laser method so that's what I'm gonna try first. I appreciate this link as it provides another option!
