Just a suggestion. When you setup for camping make sure the side of the trailer with the dump valve is not higher than the opposite side.
I found online a floor plan for a 2010 Rockwood 8317 RKSS and the bathroom is on the right side of the TT and the dump valves on every RV I have see is on the left. I believe most toilets drop straight down into the top of the black tank. Though there are some that uses a pipe with an elbow. You should be able to see which setup you have by turning off the water and look down the toilet with a flashlight. If the toilet is connected to a pipe the bottom and sides immediately under the toilet will be rounded
I have seen many members say they put extra blocks under the side with the slide out so the RV sits level. In the cases of the toilet on the opposite side, I would think that is not a good idea as many black tanks have a flat or slightly sloped bottom. Another thing to keep in mind is many holding tanks don't have much support under the bottom, so with age the belly of the tank will start sagging.
Of course, this is my opinion but others may want to think about it.
