Black Holding Tank Rinser?

[onsite]

Has anyone installed a Black Holding tank Rinser?
I check around the black tank , not much room to drill any holes in rear. Close to frame beams. Do you know of a sprayer that will work on a Passport gt 2510rb.Where it should be located? Would like have a hookup outside so I don't have to drag hose in. Seen a few on other rv's
Looked at the Tornado tank rinser but it requires a 1"3/4 hole to be cut. and the area in the rear of the tank is not easy to get to. says it shoud be opposite of valve drain.
Any info would help. Thanks

I use a flush king by camco. bought it online through wally world. no drilling required.

I too bought the tornado. I couldn't put one in both the black and grey tanks. I couldn't put them in the ends opposite the discharges so I installed them in the sides at a halfway point and they seem to do a good job. They help keep my sensors working properly.

I installed a Tornado on our past trailer. I was able to lower the tank just enough to get the hole saw connected to an air die grinder to put the hole in the end of the tank. It worked great and wasn't that hard to install. If I remember right it does say in the instructions that you can install it in the side of the tank if there is not enough room at the end of the tank.
