Hi Claire,
We have the 2005 Champange with the end washroom.
When we bought the caravan, we were new to caravaning and wanted to know how fast the water was, what temprature it got to etc, but were told that it was hot and fast.
Well, after being away in it a number of times, I can confirm that the water is very fast, and extreamly hot. As it has been mentioned it is advisable to wet yourself, wash, then rinse otherwise you will leave yourself with no water, and have to wait untill the hot water heats up again.
As my partner found out, and she was not best pleased, so now we have it of to a T
Great Caravan, and great shower, that is what sold it to us
