Query: good bang for the buck but still not as good as it could be

It's good and we use it often but it could be a lot better. It can leak, it really needs a better shut off method and or valve to make sure it doesn't leak in the van. We need to fill it up before we go since there is no water where we use it and it's leaked a few times. Also the cord is way to short, it would be easy and cheap for it to just a little longer. It's better than most of the other brands.
