1. Check Craigslist for used parts.
2. The fridge takes a LONG time to cool down. I keep 2 frozen 1/2 gallon jugs of ice that I put in the the fridge & freezer to get the cooling process started. Without them it'll take 24 hours or so on electric. Gas is faster, but still slow.
3. Without knowing a model # or at least how long it is there's no way to guess the weight.
4. Hmmm...not sure, but our 2006 had a strip with the model number on it hidden under the door's sill plate. SunlineFan will answer this one for you I'm sure
