This is the first time that I have posted anything about the mods that I have done to my van. I have done quite a few- had the van lifted, installed a toolbox on the drawer bar, moved the spare wheel to the rear bumper bar, installed a rear view camera amongst a number of other things. The one that for some silly reason I am happiest about is the latest mod. I have fitted water level senses to the toilet cassette and connected it to the setec drifter panel. Got the idea from a fellow expanda owner who I met in a caravan park. The toilet that I have would only have a light that indicated when the cassette was full (and I mean full). I have 4 kids who like to use the toilet, the only time that I would discover the cassette was full was always at night. This is even more of a problem when free camping with no dump point nearby. At least having some forewarning of the level in the cassette now, I am not going to find out in the middle of the night again.
