Air and smell from toilets when flushing

We purchased an Alliance Paradigm 370B last April and have had continuous issue with sewer smell coming up from the toilets when the valve is open during flushing. It's almost like there is a vacuum / negative pressure issue. We have tried every chemical on the market, and that's not really helping, it's the actual air coming up from the bowl when flushing. Why would this be engineered for air to travel up from the toilet and not down into the toilet when flushing? This happens from both the toilet in the master bathroom, and from the toilet in the living room.

Anyone have suggestions? We spent a lot of money on this 5th wheel and having to deal with this smell filling the living areas is really annoying.

Thank You!

A pretty good tech tip from Alliance:


My 385FL had symptom #1, the tank vent pipes on the roof were cut short, allowing sewer gas to accumulate in the “attic” and get sucked into the air conditioner and sent into the coach. Easy to check - remove the vent caps and see if the pipes go all the way up into them.

Hi, we checked that before, vent pipes are good length, no smell from AC or attic, stench rushes out of toilet when flush valve open
Thanks
