Odor under refrigerator

We have a 2006 Allegro DA. We have had an mysterious odor near the steps and in the vent chamber that is on the side wall just above the steps. It has a chemical smell that is like a mixture propane gas, battery acid, and gear lube, if that makes any sense. I have shut down the inverter for two days so the batteries are not charging, turn off the propane an bled the lines, but the smell is still there. The refrigerator is running on electric and is working fine. The next thing is to turn off the refrigerator and see if that does anything. I wouldn't think the refrigerator would put out any gases when hooked to electric. It sure is a mystery where this Odor is coming from. Possibly it could becoming from another area but that is the only place we smell it. The side wall vent must be for furnace or electrical panel to get air. Maybe a call to Tiffin may help. If you have had this problem or know a solution please advise. Thanks, John

You still have gases working in an adsorption refrigerator even when on electric (notably ammonia) but I would think you would recognize that!

Where are your batteries located? If you have cooked them, the smell is horrible.

We find that in the evening when we are using the 12v system the smell seems to increase. The gas is off and the inverter unplugged at this point while trying to find the problem. The refrigerator is working on electric but the smell is not ammonia. The batteries hold a good charge and check out god with a hydrometer. If they are cooked, would they still show as good batteries? Do you think the acid in the batteries is the culprit giving out a gas when working on 12v? If so, can the acid be changed out or wouldn't that help?
But the smell is not directly over the steps where the batteries are located. It is in the side wall vent under the refrigerator just above the steps. This area is pretty well boxed in and doesn't share air space with the batteries.

Hi. You cannot change the battery acid.

I'd say if you unplug the inverter and the batteries aren't charging, and still have the odor, its not the batteries. You could check the voltage on the batteries, should be around 13.5 to 14.0 max. If its higher. That may cause a smell.
Propane smells like rotten eggs. Not that
Is your fuel filler or tank anywhere near your odor area?
