Water line freeze in winter

[Dave2006]

I have a 2006 Keystone Springdale model 291. I am in need of the water line diagram so that I know where I can place the heat bulbs to keep the lines from freezing this winter in the past my other RV had the water lines above the floor which made it easy but now I do not know where the water lines are.
Any information would be helpful thank you

Your not going to find that anywhere that I am aware of. About all you can do is open the cabinets below the faucets and look at the lines. The shower may be a bit harder to figure out. If your coroplast is just held in place by screws you can remove some for inspection.
