I've not understood where these smells could be coming from, nor the need for fancy vents on the roof.
All pipes going into the waste tanks should be sealed from the cabin with water. All drains should have P traps that are full of water and thus prevent gasses from passing through, and the toilet should have a sealed valve that allows residual flush water to stand on top of it, also creating an air-tight seal.
So I'd make sure when you get on the road that all your drains have some water in them, and that the toilet has some water in the bowl. This is a good practice anyway as when you fill your water tanks your lines are full of air so you should run all your faucets when filling to make sure you get your tank full and all your lines full of water for maximum water carrying capability.
If you're getting stinks with all your drains full of water, you've got another problem. Somehow your waste tanks are venting into the cabin from somewhere else.
