It's Quartzsite
We generally avoid Quartzsite but we needed to dump and fill, plus shower and laundry, and with the Passport America discount you pay as much for a night's stay as you do to dump around here. We paid $22 for a spot here in November, so about double that without the discount. Their pricing structure is way too confusing, check out their website for details.
Basic RV park, all gravel, no picnic tables or any kind of division between sites.
Shower (there's only one) was clean and free, but a bit cramped.
Laundry was nice, only 3 washers and 3 dryers at $1.75 and $1.25.
There's a big selection of books and DVDs for exchange/ lending. There's also a kitchen and game area in the club house. There's also a dog run.
They have recycling here, and they even take glass.
There's free wifi but it's really weak, practically unusable.
Staff is friendly. Good for an overnight. Lots of long termers here.
