my Shappell FX50 into FX100 (sort of). And before anyone says just buy the 100...not gonna happen. Just looking for a way to make a portable cover / extension to use on the real cold AND windy days. I can do one or the other with my 50 but not both. Just want it to be easily attachable and removable....any thoughts and ideas appreciated. Also gonna figure a way to mount small heater as well, but that's down the road.Thanks
