Hello! I appreciate this forum especially for us newbies. We have had truck campers for 25 years and thoroughly enjoyed camping in them. We decided to buy a travel trailer which changes so many things. One question I have is do you recommend running a bleach solution through the fresh water tank each year? The trailer we bought is 2007 Jayco 186 and the man who sold it lied about many things so we aren't sure of the condition of things. I've read pros and cons about sanitizing the fresh water system. What do you do?
