I'm getting ready to order a new Cimarron Lite/L stove combo. This will be used for Sept. elk hunts, an upcoming moose hunt and whatever other trips my future holds. I need some advice regarding liners and screen. Do I want a screen? Do I want a liner? I guess I can always order a liner at a later date but the screen is factory installed I believe so I need to make that decision prior to ordering. If I go with a liner is a screen even needed? Thanks for the input!
