LOL, this is what I get for drinking and typing!
I, myself, for sure have soft spots, as evidenced by the incredibly sadist therapy massage lady, who I now avoid at all costs cause I'm a wussy.
I, myself, also have creAks, this how I met the sadist therapy massage lady.
My airstream floor certainly has spots that seem to give more under your weight than others, I would refer to them as soft.
My airstream floor had a large creAk at the entry door, but might have just been from the way they parked it, cause I didn't notice it before they moved it to a spot for us to stay the night in.
What I want more than anything, is to park myself, and my airstream, adjacent to a creEk, so I can hear the babbling water all night.. which would drown out my own babbling, and make my wife happy for the evening.
