Some tank configurations/dimensions are simply shallow and a PITA. Ours is like that and it doesn't take much for a pyramid to build up below the toilet. We need to do a thorough flushing before heading home otherwise it plugs up in no time on the next trip out. An in-tank flusher is better, but if you don't have one a back-flush elbow will help but won't reach everything in there. A wand down the toilet may help.
For a really stubborn build-up of solids in a tank, Liquid Drano will work great. Add about 5 gallons of water and go for a drive to make it slosh around. Tank will be like new after. Have done that twice with ours now. I think it's Thetford that makes a blavk tank cleaning chemical but the outdoor temp. needs to be something like 70F.
Prevention is the best cure. Always add 3-5 gallons of water before using the tank. And don't let it dry out and sit empty at home between trips keep a little water in it.
