When we built our house there was an alcove in the garage that we specifically put in a GFCI plug in it, this was in addition to the one already required to be elsewhere in the garage by code. We got an old deep freezer from my husband's grandmother when she passed away and it really has helped. We put the chicken from Costco out there, the meat in 1lb amount (now we actually just do 1/2 lb increments it's easier for 2 people), random other frozen meals we've put together, etc.
The space allowed for us to put shelves above it so I like that we didn't do a full fridge/freezer out there but I can understand the usage of it. My in-laws have that in their garage and it's pretty common for people to do that around here but I just didn't want to take up the space at this time for that.
If you can wiggle one in your garage even just a deep freezer we've found it to be really helpful.
