Campervan with rooftop tent

California-based rental firm Lost Campers USA announced its new double-decker campervans, featuring roof-top tents, and a greatly expanded fleet for summer travelers.

According to a press release, owners Nick and Emma Thomson have partnered with Cascadia Tents to design platform tents fitted to their Dodge Grand Caravan minivans, creating a new option called Hotel Sierra.

The tents snap onto a frame, easily collapse for travel and are accessible by a ladder. Lost Campers’ modern Sierra Class vans also feature dual-sliding doors, a double bed with privacy curtains, plenty of storage, and back seats accommodating two children’s car seats. The Hotel Sierra option comfortably sleeps four adults, with two on the roof.

Lost Campers was founded in 2007 by the Thomsons, Australian natives who saw potential in the U.S. market for budget campervans, a minivan-sized camper. The company has nearly doubled each year, offering 10 vans in 2008, 25 vans in 2009, 40 vans in 2010 and 60 vans in 2011. Self-financed until recently, the company received its first major business loan from New Resource Bank in March, allowing an expansion to 90 campervans by this summer.

Based in San Francisco, Lost Campers opened a Los Angeles satellite office in 2011, and now does 50% of its business from L.A. The Thomsons plan to open an East Coast venue later this year and acquired the new domain of www.lostcampers.com.
