probes in gray water tank ??

I agree with all of the above. In over 50 years, using all of our 5 RVs, we have never had any tank gauge in any RV that was accurate. The gauges in the Monty we now have are just as inacurate as all the rest. I learned long ago to not pay any attention to the gauges. I have no idea why the manufacturers install gauges that are not reliable.

I do have a portable gauge that I have sometimes used for years to measure the amount of propane in the Propane tanks. It works fine. Just hold it against the ouside of tank, slide it up and down and it will indicate the propane level. I suspect that someone, somwhere, has invented a gauge that would be accurate for the water tanks in an RV but why manufacturers fail to install them excapes me.

O K , not new to dry camping, we have been doing it for over 10 years, Yes I know that when the sinks burp its time to dump, however I still would like to know how to get to the gray water tank. Yes they are the Horst probes, and yes these probes have not worked since we bought the motor home 5 years ago, but I thought it would be nice to be able to check them out........

The SeeLevel gauges seem to work better than the cheapo sensors. But they cost a bit more and the entry level builders will not use them.

The new ones that you install will maybe work for a couple of years before they quit.......maybe....Not worth the trouble of replacing....... our tanks will easily go a weekend before needing to empty.

It shouldn't be too hard to find the gray tank by following the drain plumbing.

I'm assuming you dis this, but if you have a single sewer hose connection, you should be able to see where the gray tanks (sometimes smaller) piping 'Y's into the black tanks pipe and trace it from there.

Yes, I have done all the above. traced line till it went under black tank. as for the advice to forget about it, its something I want to do, have been at this long enough to know about them, just want to find the gray tank, thank anyway..
