I just meant no pooping unless you really have to. NO stinking the joint up. I didn't mean no toilet.
We have a strict "no deuce" policy in our rig. Odors aside, another benefit is that, in 17 years of ownership, I've never had a problem cleaning the black water tank, as it's mostly "water" and no "black", as it were.
And related, we also don't cook/bake/fry a single thing in our RV. About the only thing we've done is pop some popcorn in the microwave, and even that is rare.
Between no deuces and no cooking, there's no odors in our rig to speak of. A light cleaning at the end of each season and the interior smells great the next spring. I do run the roof fan often to keep fresh air moving through the rig when in use as well. If not for the dated decor (being made in 2006), you'd swear our RV was practically brand new. At least on the inside; the outside is a different story, as it has a lot of road wear (nicks, scratches, fading, etc) commensurate with nearly two decades of travel.
We really just use the trailer to sleep, prep food and change clothes. Yes, occasionally we've been rained out and had to spend a day in the RV, but that's been rare. Still, we cook under the awning so the food odors don't get inside.
I guess my point is that keeping odors out of the RV does have it's advantages, both short and long term.
