The more we read, the more we are on the road, the more we once again disagree 🥲. What do we mean exactly?
It’s about the tips on how much water you should take with you on your trip at the beginning. Like many motorhomes and campers, the Grand California has a travel position for the water tank. This means that only 20 liters of water can be filled into the tank, if more than 20 liters were filled in, this would run directly out of the tank again via an overflow. We have never used this position and probably won’t!
How much water we take with us depends, of course, on how long we’re going away and where. As mentioned in a previous post, we only use the bathroom at the Grand California. Thus, the water consumption is naturally correspondingly high. This is how you first become aware of how much water you need for rinsing and washing. If we calculate with one shower each on a weekend trip, we use a full water tank, which is equivalent to around 110 liters.
Of course, we could only take 20 liters of water and when we arrived fill the tank, in theory great, in practice totally annoying. We like to stand free or on simple pitches, some of which simply have no supply and disposal. In addition, during the winter months, many stations are closed.
There are always two arguments that people like to use for never filling the tank completely.
- Weight
- Diesel consumption
Well the weight everyone must calculate for themselves, whether it fits or not. We weighed our GC in “tour mode” and come up with 3600 kilos. We don’t care about the diesel consumption argument at this point for a purely recreational use. Possibly the Grandcali would consume half a liter less when the tank is empty, but campers know that it is not an inexpensive hobby anyway.
We keep it with the fresh water as with the toilet. Can you fill the fresh water tank, so do it. If you can empty the toilet, do it. This means that 99 percent of the time we drive off with a completely full tank. As already mentioned, everything depends heavily on the use of the van. If you always go to campsites or sites with washrooms and want to use them, you probably won’t need more than 20 liters of water for a weekend.
How do you do it ?
