I've brought a second set of keys, filled the 30 gallon gas tank, and left the automatic AC's (both of them) running with temp set at 74F. Take a 4 hour nap and get up to go out and check on my guy. Let him potty and freshen u[ his water and put him back in for another three hour nap. He loves the SUV and is very comfortable in the back cargo area where I put his giant dog pillow for him to sleep. The SUV will use about 3 gallons of gas which is nothing when taking long road trips. The problem for me is going to be when I acquire a third dog (our second Cane Corso) that I will ave to make accommodations for in the same vehicle.
