The Sugarloaf

2018 Airstream Interstate Lounge 24L

49,000 miles · Mercedes Sprinter · $30K+ in upgrades · Scottsdale, AZ

49,000 miles of family adventures.

The Sugarloaf has crossed the country side to side, top to bottom, and everywhere in between. Arizona, California, Nevada, New Mexico, Utah, and beyond. Not as a showpiece... as a family vehicle. Four kids, two adults, one van, and a philosophy: drive from hotel to hotel, stopping for adventures along the way.

No one in this family ever slept in it. That wasn't the point. The point was the drive itself.

We were driving back from the Rose Bowl Parade. My wife was driving through the mountains rocking Spotify on the stereo, the kids were giggling in back on the sofa on their iPads, and I was sitting in the middle row streaming the Rose Bowl on the big TV, listening on synced-up noise-canceling Bluetooth headphones and eating a sandwich. Everyone was less than six feet from another person.

So cool.

Coast to coast. Top to bottom.

Not your average Interstate.

Every upgrade was chosen for one purpose: making cross-country family travel effortless. No compromises.

200Ah Lithium Ion Batteries

Run everything while driving: stereo, two TVs, microwave, rear AC. Go 5-8 days without plugging in.

Auxiliary Fuel Tank

Extra 18 gallons, refillable while driving. This diesel rig goes 600-700 miles between fill-ups. Unheard of for a Class B.

🛰

Mobile Starlink

Full WiFi bubble while driving. Stream, work, browse... anywhere. Purchased day one when the tech became available.

🎵

Premium Stereo System

Big touchscreen with wireless CarPlay, upgraded speakers throughout, subwoofer. Installed by ActionVan / Sound Xpression (Mesa, AZ).

🔐

Viper SmartStart

Alarm system, remote start, GPS tracking. Start and monitor from your phone anywhere.

🚘

Airstream Air Suspension

Factory Airstream air suspension upgrade. Smoother ride, better handling, auto-leveling.

🎥

Bluetooth Headset System

Passengers watch TV on noise-canceling Bluetooth headphones synced to the onboard displays. Everyone in their own world, six feet apart.

Same price. Way more van.
