Our recommendation: opt for the weekend.
Just outside the old Western mining town of Bisbee, Arizona, is the recently reopened Shady Dell: the tricked-out trailer park of your post-WWII dreams. This isn't your standard RV hookup (which isn't to say you have a standard RV hookup)—the Shady Dell is refreshingly retro, with nine vintage trailers, a hostess with a classic '50s updo and pink flamingos as far as the eye can see...
You'll stay in your choice of antique trailers, like the rare polished-aluminum '49 Airstream or the '50 Spartanette (it's hard to pass up a female Spartan). Or, for a nautical touch, consider the grounded '47 Chris Craft Yacht (with a leopard-print interior and a Tiki head out front, perfect for entertaining guests). And when you're ready for some working-class grub, pop across the park to Dot's Diner—a trailer-turned-watering hole serving hearty Cajun grits and strawberry milkshakes from the '50s-era machine.
It's your own slice of My Name Is Earl heaven.
