Bedroom AC Causes Foul Smell In Entire Rig
I know this is an old thread, but wanted to ask if you found a fix. I have a 2020 310 GK and have the same issue with our bedroom ac only. I am thinking that depending which way the wind is blowing, the unit is somehow sucking air from the tank exhaust / vent and into the a/c system. The oder ranges from none-to-mild-to severe and I can only guess that it's dependent on the way the wind is blowing.

Bedroom AC Causes Foul Smell In Entire Rig
Hello Everyone.
I have a 2020 310 GK with dual Coleman’s Mach AC’s. Our issue started a few months ago (maybe because we haven't had the need to run our ac's till then) and I have determined it is with our bedroom ac only. I am thinking that depending which way the wind is blowing, the unit is somehow sucking air from the tank exhaust / vent and into the a/c system. Being that the 310 has the “track” ducting system, it impacts the entire rig. The oder ranges from none-to-mild-to severe and I can only guess that it's dependent on the way the wind is blowing across the tank vent on the roof. Anyone know what’s going on and more importantly, what can be done to mitigate this foul problem. Thank you for your time.

Helo, I see you are fairly new here so a big welcome. In answer to your specific question, have you checked the four AC hold down bolts? They should be between 20~40 in-lb. DO not over tighten. You can access them from inside the trailer by removing the grill then the deflector. While there, check the AC gasket between the roof and the external AC unit. There should be no gaps. If the bolts are overtightened or you can see gaps you may have to replace the gasket (not that hard of a job - but takes some work). Be carefull, there are live 120v AC lines up inside the AC if you are on shore power (or inverter or generator). If these are both good, check for signs of standing water (and blocked drain ports). Any water (from condensation) should drain out of the unit and onto the roof (and over the side). Hawaii is pretty humid and I expect you will get a lot of condensation.
There should be NO direct connection from outside air to inside. The outside air is pulled through the condenser coils then exited outside the trailer. That air never enters the trailer. The inside air is sucked into the AC through the grill and passed over the evaporator coils and blown out into the trailer (either through the dump vents on the grill or through the race trace ducting).
Just a few thoughts.
Good luck and let us know what you find.
Chris

@Hawaiian Punch, We have a 3350 RL Solitude S Class. I have been chasing an odor in our rig for two camping seasons. It is only present when we have been on the road for a few days and are using our exhaust fans. I believe the odor is being sucked in from our basement and is related to our holding tanks. I have dropped the coroplast, watched for water leaks, checked all the PVC fittings to no avail. I suspect I have an air leak in a vent pipe that is not obvious or my roof tank vents are not working as they should. I will be replacing the tank roof vents next week as my next step in trouble shooting. I will replace the vent caps with 360 Siphon vents. FWIW, Frank.

Thanks for sharing. I have read about the 360 Siphon Vents, but I'm not sure if that will address my issue. I would be interested to see how it turns out for you after you install them. If it mitigates/eliminate your issue, then that may be the route for me too. Thanks again for taking the time to reply. Much Appreciated!

Thank you for the very informative and educational post. As you may have noticed, I am not very knowledgeable about how these ac's work, but I didn't think outside air was passed into the rig, but I couldn't figure anything else as it only happens when the bedroom a/c is on. I will go through your list of possibilities and see if I find anything.
A few housekeeping notes:
1) Thank you for the top cover on my unintentional violation of community rules. Ron reached out to me too and I have addressed / apologized to him as well.
2) While my wife and I are from Hawaii, we have been on a 3-4 year / 49 State road-trip as a retirement gift to ourselves. RV's are illegal in Hawaii so we will be selling our truck and rig in 2023 after we complete the Continental 49 and return home for grandma and grandpa duty.
Thanks again for taking the time to respond. The knowledge you shared is truly appreciated.DOUG & DIANE
