Magma Crossover Single Burner Firebox
- Best for:
- Car camping, RV trips, tailgating, boating and small-group outdoor cooking where power, durability and modular cooking options (grill, griddle, pizza) matter
- Skip it if you want:
- Ultralight backpacking, minimalist hikers, or buyers on a tight budget — too heavy, bulky and expensive for pack-and-go use
Main tradeoff: High cost — premium price for the firebox and additional cooktops can make the system expensive compared with simple portable grills
Why we pack it
Sally and Justin Steele, from our own trips
The single-burner half of the pair we cook for groups on. At Indian Cove in Joshua Tree, brisket and ribs night fed forty of us off a single firebox and a double, each on its pod stand and each running off a 10-pound propane tank. Mount the firebox, connect the propane, drop on whichever top the meal needs. The grill top works like a backyard BBQ; the nonstick griddle top handles pancakes, french toast and brisket slices.
