Four questions on some rv issues

As suspected the circuit boards for both the sensors and the furnace were bad.
The fridge they determined that the lamination was delaminating and are trying to get Norcold to approve replacement.
I am going to order a trickle charger solar panel. I can just plug it into my cigarette lighter and put it in the front window.

I've got a 2007 winnebago access and my monitor panel has issues also. most of the time the potable water tank shows full when its empty. the black and grey tanks never seem to indicate correct levels. My unit has the sensors mounted on the outside of tanks and winnebago claims this gives you more accurate readings. I called Winnebago and they claim they have never had any issues with the monitor panel. the propane indicator is graduated in thirds and the guage on the tank indicates quarters. Its not worth the $99 diagnostic fee that Camping World charges to have them look at it.

When I park my rig for the winter I disconnect the chassis battery neg cable to prevent the battery from discharging. I use a low amp charger to top the battery off before we head out on the road.

On the tank level issue, I recall reading somewhere, maybe even this forum about cleaning the tanks using water softener powder. From what I remember it was a pretty thorough set of instructions. Also I recall that the writer said that the water that comes out of the grey tank after cleaning was almost black. They claimed that the tank sensors worked better after this cleaning as well. I haven't done this myself so I can't say if it works or not.

Do a search for the Geo Method. There has been a lot of discussion on RV.net and Escapees forums. We have been using the Geo method for a couple of years. We only use it third or fourth dump, normally when we will be traveling, so it can slosh around.

Group,
This web site below is what I installed on my batteries last year. I was parked for the winter and my chassis batteries went dead. There was several people in the camp that told me about this eco charger and I went on line and bought it. It took me about 10 minutes to install it myself. No problems since.

We are on our third motorhome and the monitor panel has never been accurate on any of them. Our current coach, a 2007 Monaco, has two panel, one inside on the Energy Management System console and another one in the wet bay. The one in the wet bay is most apt to be close to correct. The one inside never reads right. I dumped and cleaned out the tanks (with backflush system) last Sunday before leaving a campground. Parked the rig in my driveway while we cleaned it up. Yesterday I put it in the storage lot and checked the monitor panel. The one inside should my black as being full. Go figure. The only people I know who have working panels are the ones who have changed them out to See Level brand monitors.
