I went with replacing the fridge with the same size and I'll bring along an ice chest when I need more space. I have a portable ice maker, so I think that will come in handy. I'm replacing the A/C without heat.
I'm also pulling the furnace (storage space) and installing a quick-connect gas line for some type of catalytic or blue flame heater that I haven't purchased yet. I promise to keep two windows cracked or turn it off when I sleep! I think it will be especially handy on the "front porch" when I'm at blue grass festivals in the cold. We gather around and jam until late into the night. (Which, BTW, we'll be plugged in and I can use an electric space heater or electric blankets indoors)
So, while I'm waiting for the repairs, I'm recovering my sofa and making curtains. Can't wait to get it back and go camping!
