Our Tacoma made it to the campsites toward the back of the grounds just fine, but there was access closer to the main road for vehicles without high clearance. Great location, close enough to town or Tioga Pass if you wish to visit Yosemite. A bit buggy so be aware. We stayed 2 nights, but at two separate campsites, each of them as good.
Road was accessible for us in a Toyota Tacoma, but a Camry also made it up. It was a little crowded in the area we stayed (with 4 other caravans and trailers), as the other dirt road giving access to different campsites was more for high clearance vehicles (very steep and uneven). Hot springs in walking distance. Incredible views of the mountains. We would definitely stay here again. No waste services or restrooms, but a vault toilet was available at the hot springs less than a mile away. Would visit again!
