Mike, try placing the plugs in the sinks and shower before you empty out your waste and when on the move. Can't help with the balck waste.

Hi Mike,

You obviously have a problem. Is the vehicle pre owned or have you had it from new? If it is an older vehicle the you have to persevere with flushing the tank more often, half fill it with a tank detergent and drive around for an hour or so and then flush out. You may have to repeat this procedure until the smell disappears.

The cause of a bad smell is the continued flushing of food waste down the kitchen drain.

Ha, we discovered this phenomenon this weekend after dumping our grey water tank, 2 mins down the road and the van stank like a sewar the dumping of the water had suctioned the water traps empty so a quick trip round the van to run some water back in sorted it (I'm guessing motorhomes don't have Durgo valves fitted for some reason)

Second that put the plugs into the plug holes when driving

You will notice these smells more in the summer when its hot , not so obvious during the cooler months

Had a camper once with a large toilet holding tank and in summer when weather hot and we were driving and i had drivers window open we could smell the toilet tank in the cab But his only happened if the drivers window was open even when driving at 70mph

My therory was the external vent for the toilet tank had some part to play and by opening the window while driving the semll was circulating in the van

Have a look at your waste trap under the sinks, you may have little vents going up from them (purpose unknown), we have one under the wash basin in the bathroom which caused a stink while driving. I blocked it and solved the problem.

RVs are different from motorhomes in many respects. You may do better for answers on an RV site, though there are a few of us here.

Re the toilet smell, is it possible the seals are in need of lubrication (or even replacement)?
