what are some things i can do to....

Just getting an RV will make her stay drastically more comfortable. She can go into an air conditioned place at any time during the day, and that's nice! I would say just stock up on the water so she doesn't get dehydrated and I don't know much else you can do. Maybe bring some good food to grill or something?

^rofl

That movie is great! As is that part. hahahaha

Hmm...if she wanted to go camping somewhere else, I'm guessing that the high-maintenance / camping issue isn't the entire reason she's not thrilled with the idea. Maybe she's just not sure she wants to be running around going to concerts all day? Especially if she's not much into live shows or just not the bands that are playing. If that's the case, then I say try to make sure there's something else to do besides the shows. What if you designate some amount of time (could be an hour a day) as her time and let her choose whether she wants to check out the vendors, the art, check email in the place where they have computers, or even just hang out at the RV and read or relax or whatever. And of course, make sure she checks out the lineup to see what shows she's interested in so you can see those, especially if she might be into the jazz tent or comedy tent or something else (no pun intended) that you wouldn't necessarily have checked out otherwise.

Make sure to read the girly fashion thread and make sure she has the right clothing.

Women hate to be somewhere where they feel they aren't dressed right for the occasion. And if she is somewhat high maintenance then she will care about this. Here is the thead - maybe you could suggest she read it

My wife is high maintenance also. Heres what I would do. Leave her at home. This kind of problem could create negative vibes. Take her camping for 8 days when you get back...build a fire...roast some mallows...tell a ghost story...sing her every Willie Nelson song you can think of...then make love!

I want to add something even though it kinda ties in with what I said earlier...

I think the most important thing you can do is be willing to make some sacrifices. Whether it's missing a show you would have chosen to see, hanging out in back so you can sit and have room to breathe at a show you would have chosen to be up front for, anything like that. If she ends up unhappy it won't be a pleasant experience for you either, so being flexible and open-minded will keep you BOTH happy in the end!

My wife is a trooper when it comes to having a good time, yet on my first year I geared up on some stuff to make sure she would be as comfortable as we could arrange and we could both enjoy it.

I am a major planner, so as I was researching and buying stuff I got some eye rolling from her but as it turned out stuff was quite handy and she appreciated the effort I put into her comfort.

Couple things I would suggest:
Get he a sun hat, the sun can be brutal, my wife doesn't like to wear hats, but I bought one and brought it and by 2pm Thursday it was her new best friend.

Good bed and sun canopy: As you have an RV you won't need an air matress but if the RV doesn't come with a sun canopy, consider a cheaper Eazy-up. That way you won't get cabin fever in your camper and you can socialize without getting fried.

A blanket is handy and they have nice ones for the beach that are damp resistant nylon on one side, cloth on the other and you can zip them up into a hand bag and use them to carry your sunblock and water. Very handy for evening shows because they keep you mobile and traveling light.

Also, if you are at all an old fart like me a blanket lacks the back support that will let you relax better on day 3 or so.. or if we get a lot of rain a blanket would just soak so a low chair would keep your butt off the mud.. you might want to get a low-back folding chair for the day shows.. I recommend these with a backpack built in

Also might consider a Camelback, you can get by with a refillable water bottle as there is waterstations inside centeroo, but they use well water and some folks think it tastes bad. Last thing you want is your wife not drinking enough water because tastes funny. If you get a 70oz camelback you can put ice in it and bottled water every morning and have cool water most the day.

This year I am going to get one of those personal misters and try it out. Some folks had one near us while camping out to get a good spot for OCMS and it was really nice when you don't want to loose your spot going to the Mister tents.

small first aid kit with:
spray sunblock, aloe, immodium, asprin, blister care, bandaids, antacids, etc.

Getting a wide brimmed hat is great advice. I never ever wear hats and hate the way they look and feel on me, but I got one of those guys khaki fishing hats and becomes my best friend for Roo every year

Two lightweight Centeroo legal chairs. Standing all day or even sitting on a blanket, gets old and uncomfortable after awhile.

also give her a bandana or a doctors mask for the dust,the dust is a real killer and for someone who already doesnt wanna be there it will drive them crazy. so keeping dust out of the lungs is a major plus
