2011 Montana black tank problems
I have a new 2011 Montana 3150RL fifth wheel, and I have been having some problems with the black tank since the first time I dumped it.
It seems to drain slower than what I have experienced with all the other rv's I have owned, in that the discharge does not have much force and the flow fills only about 1/2 of the transparent elbow going into the dump station drain.
After dumping, the monitor will show either 1/3, 2/3, or Full. It varies, but never shows empty. If it reads 2/3 full and I hold the button in for a few seconds, the 2/3 light will gradually fade out and it will stay on 1/3.
After using the tank rinse-out until the water runs clear, it still will not go to empty. However, if I fill the tank with water using the rinse-out and dump again, it drains much faster than before. It gushes out with a lot of force and fills the transparent elbow completely. The monitor will then read empty, but will go back to 1/2 or 2/3 full again after just a few toilet flushes.
Before risking an expensive repair bill (Keystone says they will not cover it unless a problem is found with the tank or monitor system), I would like to know if any other Montana owners have run into similar problems.
I do know that black tank monitors are norotious for erroneous readings, but mine was malfunctioning brand new before the tanks had a chance to scum up (ulness just one tankfull of waste will do that).
Camping World, where I purchased it, says they cannot duplicate the problem, but it happens every time I use it, but then I have not seen them take any notes when I describe the problem either.
