Foul Smell in RV
I have a foul smell in my RV. I went camping this weekend in a travel trailer and there was an awful, foul smell whenever the water turned on. My camper is brand new. Do you know what could cause the terrible smell or what I can do to get rid of it?

It could be there is no water in one of the P-traps.
The way drains work, the P-traps are configured so that they hold water. That water acts as a barrier so gasses from the holding tanks don?t come back into the trailer. With the water gone, the barrier is gone.
When you turn on the water and some goes down the drain, it displaces gasses in the holding tank. Normally, they should go out the vents. However, if you have a dry P-trap, the gasses could be coming up the drain and into the rig.
As to how or why the P-traps would dry out, if you haven't used them for a couple of weeks or so, it could have evaporated. Or, it could have sloshed out when going around turns or driving up and down hills.
Your shower drain could be the culprit.
Running some water down all the drains may help.Go to the RV Life and Travel blog.
