OK, Al snuck out there while I was cutting out dresses for the twins and started some serious snooping.
He took the vent out and was able to reach the PROBLEM! It was 16 inches from the heater vent. He was able, to JUST get his arm in under the carpet and reach and touch the nasty!
It is NOT a Lag bolt (just felt like it through the carpet). It is a phillips head screw, LARGE screw, and it is sticking up about 1/8 of an inch. He tried a lot of stuff, like vice grips, cause it turns just a bit, channel locks, even took a screw driver, cut part of it off to make smaller and tried turning it. no go on any of it.
He cannot get it to turn enough (cause he could JUST reach it) to remove it.
He then went to a metal plate over the screw and beat on it a bit, hoping to break it off, and that did not work either.
So, it is still there, he is worn out, and has a scrapped up arm to show for it. We are gonna try to put the rug and the little wicker storage cabinet in such a way that we don't continually walk on it while we are gone.
Calling the service center for suggestions, etc, might be the next step, but at this point, the LAKE is NEXT~!!! ohh yea!
The carpet will have to be cut (and then seam taped with that hot glue tape stuff) or pulled up from the sides and then tacked back down to get at it.
Let me tell you, it was not for lack of effort!
