Fire pits split into gas and wood-burning types. A gas fire pit has a propane connection and lava rock or glass to handle, while a wood burner just needs ash cleared. Both have a bowl or basin to protect and can be surprisingly heavy if made of steel or stone.
Pro tip: Bag lava rock and fire glass separately so they do not scratch the bowl or scatter through the truck.
Watch out: Transport a propane tank separately, upright, and ventilated, never sealed inside a hot vehicle.
