For our heavy loaders (the Revo and Granvia), I load up to 38psi on the tires. 35 on all the others.

I'm at 45 psi for the CR-V, the sedan, 50. Ride is stiff, but only annoying over potholes.

The car gets higher pressure because the tire sidewalls are much softer. There's still some squidge in the tires, even at that pressure, and the sidewalls still roll under in hard cornering. Can't wait till these wear down so I can put on proper rubber.

The 3,000 - 6,000 watts are estimates based on the load draw of electric AC compressors in hybrids... but are relatively accurate as far as horsepower loss goes (6kw equals 8hp)... perhaps even on the low side.

Dyno data from overseas suggests between 8-15 hp lost from AC compressor use. I recall one dyno we did at Speedlab which showed about 10 hp loss on a Honda Civic from turning the AC on.

Yes, perhaps it's better to simply install a wall AC into your car, then run a separate alternator for it.
