How many gallons of water does an rv hold on an average

Last Updated on :

One of the important aspects of motorhomes or rv’s is that they have water holding  or storage tanks. When you have direct water supply at campsite, you may not be much worried about water. But, while you are dry camping, the storage and holding tank importance cannot be less than anything else. A bigger rv comes with a larger tank as compared to smaller ones like class B rv.

Understanding the rv tank size is important so that you can plan accordingly for your camping. Refiling water in fresh water tank, draining or emptying grey or black water tanks needs proper planning. In this article lets see how big fresh water tanks, grey and black water are for various rv types.

Fresh water tank capacity of different RV’s

Rving and water storage cannot be separated. Specially, if you are dry camping or boondocking. A larger tank for fresh water is desired by every camper. When you don’t have the water supply directly connected from the source like a campsite, the only option you have is the fresh water tank in your rv. Most motorhomes come with rv fresh water tanks that are good enough for you.

But, you know how things happen. I myself camp with a big fresh water tank but almost every time end up regretting about the tanks size. No matter how big is your tank, you always end up finishing it. Well, all rvers may not agree with this though. But , you yourself at least will agree (since you are here, searching for how much could be your rv tank capacity and what other option you have).

Lets see average fresh water tank capacity for various types of rvs. It obliviously is different for different types. But, the size has to do a lot with the length of the rv. Why length? well more the length, more is the number people it can accommodate. And, for more people you obviously need more water and hence bigger is the tank size, that is logical.

Class A rvs are bigger, accommodate more people and hence they will normally have larger tanks. Fifth wheels too have bigger fresh water tanks unlike smaller travel trailers. Class C and class B will have relatively lesser sized tanks.

  • On an average a class A rv is normally equipped with a fresh water tank of size 70-100 gallons
  •  Class C rv is normally equipped with a fresh water tank of size 35-55 gallons on an average
  • On an average a class B rv is normally equipped with a fresh water tank of size 18-40 gallons
  • Fifth wheel is normally equipped with a fresh water tank of size 60-75 gallons on an average
  • On an average a smaller travel trailer is normally equipped with a fresh water tank of size 40-60 gallons

Lets see some of the examples of various types of motorhomes, travel trailers and their fresh water tank sizes.

Class A RV’s are the best you can get. Bigger bedrooms, spacious kitchen and numerous amenities. They also have the biggest fresh water tanks. You wouldn’t get such sized fresh water tanks in any other rv types. A 100 gallon fresh water tank is much more and your camping should be worry free.

Most class A motorhome will be equipped with fresh water tanks that are par with 75 gallons. Even the grey and black water tanks in class A are bigger. Price in class A will be much more and not all of us can have this luxurious and spacious motorhomes. Take a look at this article that discussed average prices of different types of RV’s.

Average Fresh want tank size in class C motorhomes

Class C motorhomes are smaller than class A rv’s. They tend to be pricey too and are also costlier than a fifth wheels or even larger travel trailers. Lets see some class c rv examples with their fresh water tank sizes. Class C rv’s, do not have very big fresh water tanks but should be okay to camp for a smaller family.

In case your RV water tank storage isn’t great then you have an option to use portable tank as well. Do check this water storage solution by AQUATANK ( amazon.com link), its perfect if you are dry camping.

A 35-40 fresh water tank may not be considered very big considering the amount of water may be needed for camping. Most class C rv’s will have fresh water tanks that range between 35 gallons to around 55 gallons. But, then again it depends on how big and model of your class C rv. The bigger rv with more amenities and bigger tank size will cost your more and if your budget is up for it then well and good.

How much is the size of fresh water tank in class B rv’s

Class B motorhome or smaller camper van’s and have the smaller fresh water tanks. These kind of motorhome are suited for couples or solo campers. There are many class B manufacturers that build such vans across United States and Canada. With minimal amenities and very small fresh water tanks, these kind of rv’s simply don’t suit for bigger families. Or even for couple with kids, these kind of motorhomes may not be enough.

They have water tanks that are way lesser in size as compared to class A, or class C or even travel trailer. Mostly the class B rvs will have fresh water tanks that are some-what around 30 gallons or so. Bigger ones may have a little above 50 gallons but not beyond that. They are designed smaller and hence they cannot have those big 70 gallons or 80 gallons in them. Here are some example of class B rv’s and their fresh water tank size in gallons. With such smaller tanks, it is very difficult to do things like taking shower or washing dishes etc.
