How does 25lb of lovin' sound to you? If you're looking for a basecamp-class stove that has everything including the kitchen sink, Coleman has a not-so-little somethin-somethin for ya.
The Rendezvous 2-burner is a massive suitcase style stove that opens to the side. You can remove the lid easily by sliding it off. To help you carry this monster there is a comfortable large diameter rotating handle on top. You want features? We got features: the lid doubles as a sink and food storage area with adjustable bins, an anti-microbial cutting board and a griddle for eggs and pancakes. There's even a little rail on the front with hooks to hang utensils on.
The Rendezvous takes propane in any size with included adapters. But does it burn? Yeah baby! The battery-operated ignition fires it up effortlessly, and the flames are totally adjustable from low simmer to full afterburner. If you can't cook like a pro on this thing you may be hopeless. The Rendezvous might be over the top for a lot of folks, but if you don't mind the weight, space and cost of this behemoth it will make feeding time at your zoo a pleasure.
