RV Description

ONLY 6,000 MILES ON ODOMETER: IDEAL FOR CROSS COUNTRY TRAVEL OR LONG_TERM LIVING FOR THE SOLO TRAVELER


With extensive internal insulation, 800 Watts of solar power, and ultra efficient heat pump Harper was designed and built by a company for long term living. With it's stealth design, the van can be used in locations that would be prohibitive for the typical Type B van or other RVs. With 800 Watts of rooftop solar, 1000 Watt inverter, and 7500 Watt/hour battery system Harper is truly off grid. No need to pay for electrical hookups. On sunny hot days you have enough solar power to run the ac or heat without draining the batteries.



Bought in November, 2024 and built out for the last 2 months by a professional van build company (Pro Van Kits) Harper combines craftsmanship, design, and engineering. Designed for a solo traveler, the van has just about anything you would need to travel and live in. The design was refined by the company owners who have spent several months on the road in their custom built vans and built 24 vans in past 3 years.

    Our van design philosophy is to keep it simple. We've simplified complex electrical systems, eliminated unnecessary equipment, and focused on the simple basics. What would take weeks to accomplish by hand we did via CAD and CNC in just days. Harper was precision machined in just days, with all the cabinetry, walls, and ceiling installed in just 2 weeks.
