I think some of us have experienced some level of it...but have simply dealt with it.
Back before we gutted Peanut, we realized it was moldy, rotty, stinky and dusty--
After I sat in it for an hour my face began to heat up, I began to cough, and I had to go in the house and shower off--even then, I coughed and snorked that whole night and another day and night. I could hardly even step inside
Peanut's door until Paul got it completely gutted and had super-washed the whole interior twice. (some of the things pulled out shown below).
Then he painted the inside with Kilz and sealed the raw
fiberglass. (He didn't
paint the ceiling except in the Putin, where we took out the old vent and patched ceiling and roof.
By that time the sick-camper syndrome stuff was cleaned out and sealed off, so I could go in there again and my face quit burning and I quit coughing.
But we never considered it "sick camper syndrome" ("sick building syndrome" or something we couldn't deal with...we just dealt with it.
I think most of us do it that way--find the problem, clean it up, repair, replace, seal, and voila.
Sick camper cured.
