Yes, you've got it nailed. Also please pit right next to us.
A/C? Nice, but do you mean you're bringing a huge unit that'll sit outside in your pit and blow cool air over you (and us, right next door)? I think that's overkill. Last SpeedWeek we were pitted next to Ack Attack -- they had an interesting setup: CO2 bottle pressurizing a water tank that fed lines with tiny holes -- so they had a mister going for hours at a time. I sat with them a few times -- but would have been okay without it.
Generator -- sure, if you need all that much AC power. I've got a 400 watt inverter mounted in the bed of my pickup -- plenty for charging laptop batteries, rechargeable tool batteries.
Mircowave? Where do you think you're going? This is the Bonneville Salt Flats, for gosh sakes! There's an abundance of natural heat (read: sunshine) to warm your sandwiches. Bring a thermos to carry hot coffee from the motel in the morning -- you'll drink only about half the cup before you switch to sports drink about 9AM.
Refrigerator? Nah, use ice -- be a real racer. The melted ice can be ued to cool the intercooler, too, or to soak rags in to wrap around your neck after runs.
A/C in the trailer? I suppose so, if you really must -- but again, it'll require you to run the generator, make noise, use fuel, and sit inside and miss the runs and the visitors. Go circulate in the crowd. Perhaps the most-often asked question as you walk around among the racers, the pits, the lines in pre-stage and staging: "Hi -- need something to drink?"
Part of the fun of Bonneville is the long lines at the icemachines in the motels each morning as everyone ignores the "Please don't fill coolers" signs and fills the coolers. . .
