Are there any RV toilets with a P trap?

I'm getting tired of trying different black tank deodorizing solutions.. I can't seem to find one that knocks out the odors as well as breaks the junk down. I've tried at least 4 different products, and while most work for a few days, they never last the whole tank.

My question is, are there any RV toilets that have a standard house P trap in them? I'm guessing that would eliminate the smells and allow the use of any black tank solution.

I'm all ears for any additional solutions as well.

Thanks!

    It's not the water that keeps the smell in on an RV toilet. It is the seal on the valve that does that. Water standing in the RV toilet is only there because the rubber seal won't allow it to go by. Residential toilets do have traps -- just not p-traps -- they are s-traps.

    I don't know of any RV toilets with traps.
