Camper toilet paper is made especially for easy breakdown in an RV sewage system! It is supposed to degrade faster than ordinary household toilet paper! I do not know the particular regulations regarding the use of these types of papers but would hazard a guess that many state parks may have made it mandatory!
However, I don't think you have to worry about the TP troopers bustin in and dragging you off of the loo if you use ordinary toilet paper! But it might clog up the works in your RV toilet which would be even worse! LOL!
