Hi Peggie, while I got you on the line, I'm going with the Ronco B126
30 gal. Two 1.5" dip tubes, 1.5" fill, 3/4" vent., all top mounted.
With the idea of keeping the number of penetrations to a minimum, is
it necessary to have a clean out port? If yes, how about just a 3"
boss with a plug instead of a port and plate?

The Snake River system, hands down. I've yet to see any internal sensor
last more than a few years...whereas, because the Snake River senders
never come in contact with tank contents, they last literally for
decades. The cost is another consideration...the only SeaLand system
under $200 is their TankWatch I (about $50), which only lets you know
when the tank is full (which I consider next to useless unless you spend
all your time parked next to a pumpout). The single tank Snake River
Mini for about $100 provides true 1/4, 1/2, 3/4 and full readings...and
their 4 tank system that lets you combine waste water and diesel in a
single system is less than the price of any other single tank monitor.
No problem if any of the tanks are aluminum either...Snake River also
has internal senders that never come in contact with the tank contents
because they're encased in PVC...internal and external senders can be
mixed and matched.

Fwiw, I've had several SeaLand Tankwatch systems--their expensive ones.
I'd never have anything but a Snake River system again.
