If you're looking for a comfortable and safe SUV that
stays in the low $ 40K range
loaded, you might consider an Acura RDX or even a non-luxury
model such as the Ford Edge or Jeep Grand Cherokee.
We realised we could easily modify our
model to work out the size dependent gains for an unoccupied house by simply taking the fixed gains, and omitting the occupancy dependent ones — the refrigeration, and standby
loads stay, whereas the cooking, washing, lighting go, as do the losses from incoming cold water and evaporation.
