Yeah, I was thinking about See Level too. I'm sure it's economics, but when you're spending 40-50K or a lot more on a towable an extra $300 is easily buried in the overall cost. I, for one, would gladly spend the relatively little bit extra for a system that works.

For us it's actually accurate gray water levels that would be helpful. As JRTJH stated, the black water is pretty easy to keep track of.
