ABS will be cheaper, it's already black, and it doesn't degrade like PVC with sun exposure. Downside is that you don't have the variety of fittings that are available for PVC, but if you keep it simple that is not a problem. On the roof rack, you can probably skip the pump and use gravity feed if you don't need a spray.I am going to use the largest black PVC pipe with bike pump valve on the top, nozzle hose on the bottom.
.I was wondering if anyone ever made their own road shower type device?
I'd vote for a more portable option. Ever since I made this for about $85, I've lost all desire for a vehicle mounted system.
Pack it empty, dunk it in a stream, heat it on a fire or a burner and wander off to a nice private spot without creating mud at your feet where you step into your truck.
I often camp near water and enjoy stoking a fire, and in this case, unlimited hot water is usually on tap. Really nice for washing dishes, dogs, gear and people.
