Black Tank Backing Up-Please help!

So we've gone dry camping twice in a new to me 2002 Cougar Fifth wheel. Both times we've had a blacktank/toilet backup issue. Emptying the black tank does not help. Yes I know about putting enough water in there and all that. It appears the solids/paper are just not making it into the tank and they back up by the second day to the toilet. The first time I poked it from the top with a rotorooter type snake while my buddy banged on the tank from the bottom in the area where the pipe goes in and it finally went. This last time I just poked it and it seemed to go easier this time but I'm not sure if it's a bad design or what. There are two 45 degree elbows on the way down because the tank is not directly under the toilet. I used to have a TT which never had this issue. How hard is it to remove the black tank? Any ideas? Thanks....
