A definite fix, but it takes some time and plumbing know-how are HepVo waterless traps. I learned about these from a friend of mine who is a plumber. For RVs, these not just replace the P traps, but the air admittance valves. Use these for the sink and tub... no more stink from the gray tank. For the black tank, make sure the toilet's ball valve is sealed (olive oil), and that cures that.
Of course, it doesn't hurt to make sure the vents are unobstructed.
