Why we pack it

Sally and Justin Steele, from our own trips

When a trip outgrows one picnic table, we switch to these. This spring at Indian Cove in Joshua Tree, brisket and ribs night fed forty of us off our Magma Crossovers: a single-burner firebox and a double, each up on its pod stand, each running off a 10-pound propane tank.

The interchangeable tops are the reason. The grill top runs like a backyard BBQ for corn, burgers and hot dogs, and the nonstick griddle top puts out pancakes faster than forty people can eat them. Two grills for forty sounds thin until you remember they only finish food. In bear country the grease traps come out every night.

Tradeoffs

  • Steep learning curve for the pizza-oven attachment; can run extremely hot and char food without practiceBob Vila
  • No built-in fold-up leg support (table-top only); requires stable surface or separate stand/mountTales of a Mountain Mama

Questions (1)
Is it worth the price over cheaper alternatives?
For frequent vehicle-based campers and tailgaters who value marine-grade build, high heat and modular versatility, the durability and functionality can justify the premium; budget buyers or solo/lightweight campers will find better value in simpler two-burner stoves.
