Smaller living means giving up your escalade XLT that has been stretched. If you really need a SUV I found that the Subaru and Suzuki has offering that fit in a tiny garage or are smaller and overall very comfortable. But there are other options. If you live where it's warmer, a motorcycle is a better option. A bike takes very little space, you can fit 3 of them in a 1 car garage and they cost less to run, own and maintain.
I can carry all our family groceries home on my Motorcycle, go to work with my laptop and other gear and tools and easily go off on a weekend trip with the wife. We save money and space.
