I have to admit . . . if I were coming from Maine, I would fly.
I would make a merciless shopping list, fly in to Reno, pick up a box truck (to be both tent and shade), shop for a couple of hours at Reno's many stores, possibly sleep one night at a reasonably priced hotel, and drive the 2 hours to the playa. Why sleep first? Because shopping might take longer than one would imagine, especially
as a new Burner . . . then add the minimum of 2 hours' drive (more if you're coming in on the same day as 50,000 others) plus at least 3-5 hours in line before you're even into the event, and another hour to find your camp or pick an open site.

If you're a practiced road-tripper and can be gone from home the extra days it will take to drive both ways, well! You know your own mind.
As people have already said: plan for at least
50% of your friends to drop out of your plans before June. It's typical! The Burn can be intimidating and expensive, and people tend to fall by the wayside as the months pass.
Have a plan B that involves you going alone if absolutely necessary . . . or join a camp, and plan to meet up with them on the playa.
