Thanks I'll check out the battery levels and the voltage, the voltage
gauge seems to read ok, and will check the fan. This is definitely
not wafting up from the rear, that's what we thought at first since we
first noticed it with the trailer back there, but even with no trailer
it is exactly the same amount of stink from the windows while driving.
I'm almost positive it is not some other fluid in the car as I'm
familiar with their smells. Also it is definitely not that rotten-egg
smell associated with cat convertors, so pretty sure it's not an
exhaust leak, just doesn't smell like an exhaust, fuel or cat conv.
odor. The racoon joke is almost what I thought at first, I started
hunting for some dead cat under the hood. I suppose their could be an
animal hidden somewhere that I can't see it, this did happen first
when we left a camping area, I'll look some more.
