RE: What size freezer
I have two uprights, a 19 and 17 foot models. They are both full of something all year long. I should mention that I live on a farm and we butcher a beef about every other year; have a large garden; fish and kill a few deers each year as well. A seven footer seems very small to me.
One thing I have against uprights, is sometimes you have to watch little ones with them. I have a 8 year old that will slam the door shut and the door pops open behind him.
