Man, an hour and a half has got to be OCD when it comes to setting up. Even in a campground I've never been to before, I can stop on the road and check out the site in a minute or two for obstructions, know where I want to set up, get in, level, slide out, hook up, get out the ground carpets and the chairs and pull out the awnings in around 10 minutes. What is he doing? Raking the site, getting on his hands and knees with scissors making sure the grass is cut to exactly the same length? The best way to shorten set up time - stop overthinking it.
