If you want an upgrade check 9barista. Same form-factor as bialetti but it makes an actual espresso with right temperature and pressure. And it even comes with an adapter plate for gas burner.
I also use a moka only when camping (French press and espresso machine at home).
Why it’s great for camping:
1. Indestructible
2. Cheaply found at a garage sale (no worries if it gets lost in a pile of camping gear)
3. Takes up less volume than a French press
4. When camping, everything tastes better. Even “ok” coffee is a luxury
All this to say: a $500 device is a tough sell for camping
