Antifreeze recommendations

Welcome to the forums. Its an excellent place to ask questions like this. Is there no one you can ask for help to show you what and how to do this? Its not complicated but you need to learn as much about your trailer as you possibly can to be able to fix things and maintain your rig yourself. It will cost an arm and a leg if you take it to an RV place for this type of stuff......things you need to do yourself. Even when you are at a campground there may be someone willing to show you a thing or 2 if you ask. RVers are a friendly bunch and are usually willing to help out someone that is in need. Good luck.
