The rivets I lose are always from the same place. I think it's just an alignment issue. The stress at that particular point shears the rivets. It's not a big deal. There are thousands of rivets in an Airstream. Missing one or two will not make any difference. Keep replacing them and don't worry about it, or don't bother replacing them.
If the empty rivet hole bothers you, glue rivet head in it.
