hi, wondering if anyone has any input for a tabletop lp grill that could be used on a pontoon? doesn't need to have specific mounts to add on the railing of the pontoon {but would consider it if the unit is a good one} as i believe i could make some type of shelf myself and secure a grill to that. better to have one with more than one burner for better heat control? other options that a person should look for? how easy to clean? best for not rusting ? all ideas or advice would be appreciated. thanks
