I have permanently added an 'extra' valve on trailer dump line for many years/several trailers.
I use it to back flush black with grey
I use it to combine grey/galley
I use it to combine all three...black/grey/galley for extended camping
Waste tank is a waste tank..grey is just as nasty as black.
The type of TP is not your blockage issue.
Liquid to solids ratio is.......need more liquid and dump when tanks are near full (fuller the better....high volume/weight increases the 'whoosh' factor)

Nothing dissolves in the toilet because there are little bacteria working. A healthy black tank should be a seething cauldron of bacteria!

You guys talking about not using enough water are barking up the wrong tree. It's a plumbing problem not a water problem.
The OP's trailer is probably plumbed in a similar fashion to mine. The black and gray tanks are side by side with the drains on the sides of the tanks facing each other and are are coupled with a tee. From tee there are two more 90 degree turns before the exit point. So waste has to essentially make four 90 degree turns within a very short span. Flow rate and velocity are greatly reduced as a result.
I've been doing as the OP suggested for years and it works great.
Those of you that have a tank with a straight shot out the end won't have this problem.

Perhaps you need to use more water when flushing.
