When we first camped in our Wildcat MAXX we plugged the toilet. It took a bit of work to get it opened up. I totally agree---MORE WATER is your answer. We have never had another blockage since we started to fill the bowl 2/3"s to 3/4's full of water before flushing solids. As others have said, don't bother "fixing" the toilet, fix your flushing process, or live with a plugged toilet from time to time. As the old saying goes--"it is what it is"!!!
