lot of posts on how to, where to mount, which one is best ect... let here about what you cook in them, and how do you go about planning to make sure it is warm enough (hot) for your lunch stop.
Trial and error is how we do it My old piped MtMax could cook frozen food in just a couple hours. Every sled is different and you just have to see how long of what kind of riding it takes.
What to cook.. We like to make wraps. Flour shells with cheese, turkey, ham....Prime Rib from the night before Those only take about 30-45 minutes and the ones on the bottom are nice and hot. Eric
