Hi all, Has anyone ever seen a F1 car with a 100ltr water tank strapped to it? Of course, it would have an effect on performance. In these days of eco awareness, with attacks on diesel powered vehicles coming from every corner, it is not only sensible to travel empty, or with a small amount of water, but less selfish. Just because we can afford a motorhome doesn't mean we can take the P**s. We tend not to bring that home with us. All the Best, Ian.
