Mine has the standard set of mods, and works great from mid May until maybe early October (on warm days), but once we start seeing temps below 40 outside, the thing just won't come up to temp.
We ended up running a weed burner under the water bowl last Thanksgiving to get the turkeys (mostly) done.
I've heard hot water heater blankets suggested, or flashing tin rings around the bottom to keep wind from blowing up from the bottom...
Has anybody tried either of these (or both together) with success?
I don't like the thought of going another winter without any home-smoked meat! (I guess it would still work for jerkey at the low temps).
