Yep aware of the installation instructions, I was asking the op if there was a reason for a permanent install like that. It could be vandalized, damaged or stolen if this is a moving rv and not a stationary tiny home. Also just adds to the stereotype of the skoolie image. A bracket on the back with a waterline quick connect would mean the unit could be safely stored inside until needed and hooked up in minutes.
