Have never seen sight gauges on waste holding tanks (water and fuel
only). I expect that sight gauge would get nasty and clogged quickly!
I did used to have rotomolded plastic holding tanks that were translucent...a strong flash light made liquid level in the tank really obvious.
Tank Tenders are a bit pricey, but excellent quality gear
. Cost looks a lot better amortized over their long life span.
