We are taking our new travel trailer out for the first time this weekend and I am wondering if there are any words of advice from "old hats" who have been doing this a while. Basically I need to know what we need to know URGENTLY...for example, things like making sure we disinfect the water tank before we use it, stuff like that. I figure we will learn the hard way on the smaller issues, but what do we need to know to keep ourselves SAFE? Thanks in advance for any advice. We were tent campers when young and went a couple times in a pop-up but never been in a travel trailer before.
