Hi folks. Ok so we bought a new 5th wheel last fall and when the season was over I winterized the rig. No I'm not a complete newbie as we shared a Class A with my in-laws for years. BUT as I was thinking about spring coming and getting ready for our first outing I couldn't remember if I actually drained the shower when I did all the rest. I drained the fresh water, water heater and both facets in kitchen and bath but I think I forgot the shower plumbing. My question is should I be worried about the lines getting frozen over the winter? For sure a rookie mistake.
