Dropped one side of the underbelly today and installed a turbo rinser on my gray tank. I had to install it on the same face as the probes are installed since there was no room to work on any other side. I routed the included clear hose to the side of the dump mast valve so it would be easy to get to.
I sliced the belly coroplast along a wood stringer (that was secured by a metal strip) so I did not have to drop the entire thing.
Total time from starting to drop the panel to the last screw was about 2 hours.
Easy install. Hardest part was buying the 1 3/4 inch hole saw at Lowes.
