I’m SOOO glad its not just us, although I think you have us beat. We have 8 or 9.
I have 3 that are “mine” that range from a single burner that is simplicity itself (gets used on the sailboat a lot), to a two burner with an oven (camping trips with the grand kids).
The oldest backpacking stove I refer to as “the bomb”. I keep throwing it away and my husband keeps retrieving it - it was his first backpacking stove.
At least if the electricity goes or we’re forced to abandon civilization, we’ll eat.
If I knew how old your husband is, I would try to guess which was his first stove, if he is very mature, then I would guess a Svea 123.
