Anyone bought used rig with musty smells or dog odors?

I saw that there is another one in a driveable distance so we may go take a look at that one.....

In terms of cigarette odors....ZorbX works wonders. Our car had a ciagarettte smell and we got ried of it by covering every surface with it. However...there was the smell of ZorbX for a while but it wore off eventually.
