I'm pretty immune to weather so I don't need it to stay 70 deg or anything... just a little warmer in the winter.
If you’re looking to get into the 55-65 degree neighborhood, with the outside air around 1 or so, and judging how you described your garage, a 45k BTU unit would be more than enough. A 65K BTU unit would cycle too much, as it would heat the garage to fast, more is not always better.
A ceiling fan mounted at the opposite end of the garage will help with circulation also....Just my 2 cents....Good Luck....
