I seem to find it's not the waste traps that are a problem Jim, but the tank overflow vent. Trying to work out if I can get a trap device for that.
hmm.. never thought of that, and frankly haven't smelled it from the Hymer.. yet..
I think the tank has a pipe from the top and pointing down to the ground... must have a butchers.
on the RV , both black and grey tanks had stench pipes up to the roof .. which would pull fresh air into the tanks with the naturally draft ..
