Know your tanks
How much can you hold?
How much can your fresh, gray, and black tanks hold is something every RVer figures out. Here is an insider tip…most likely your black and grey indicators will fail you at some point. Sorry. So after a few trips you should get a feel for how much your rig can hold and do some anticipatory math if you are going to Boondock for any length of time.
Do your best to prevent water from going in your grey tank. You might be surprised how fast your grey tank can fill. Little tricks like putting a small container in your sink for washing dishes can help you prevent water from ever getting in your tank. You can take what is in the container and discard outside. That is, if you are not using chemicals that are harmful to the environment around you. Especially if you are camping by a lake or stream.
Fresh Water – Tank and Potable
Your RV will have a fresh water holding tank but remember to bring gallon size in your rig and if you are out for an extended amount of time it may be wise to bring large 5 gallon potable water as well. This way you will have plenty of water for drinking and household needs.
Is your Fresh water really…Fresh?
Cleaning out your fresh water tanks on a regular basis is not a bad idea. Find a system you like to clean them. We use a ratio of bleach to water and then drive to “swish” the water then dump the water…refill and dump again to be sure all chemicals are gone. Find something that works for you so you can depend on the tank to deliver you the fresh water you are expecting.
