Absolutely camp. The nearest area that remotely resembles civilization is like half an hour drive away, and it's close to an hour drive if you want more than 2 choices for restaurants.

I'd even say upgrade to the nicest camp you're willing to afford. Everything above GA comes with shuttles to/from the venue so you can avoid the half hour uphill hike back to GA after the show and dedicated showers that won't have hour long lines. Terrance and Glamping lets you drive in/out whenever (but there's really no reason to since there's nothing nearby).

Important part is bringing in enough food and water for the whole weekend. There's typical fest food and water stations in the venue, but there's practically nothing at the campgrounds. Highly recommend some sort of shade/tarp and multiple batteries/mini solar panels. Assume you're actually properly camping since it's really inconvenient to do anything else.

But it's also probably the nicest camping experience of any camp fest. Pretty much stayed friends with all my neighbors. Everyone at the Gorge is pretty much stuck there form start to end, so everyone socializes and shares/trades resources.
