The Tesla Semi all-electric battery-powered Class 8 semi-trailer truck isn’t set to hit the road until 2021, but this early, a London-based startup has designed a luxurious motorhome based on this beast.

The firm called Vanlifer, which designs campervans for clients all over the world, has revealed a concept motorhome build mounted onto the back of the Tesla Semi. Company founder Jason H. claims his Tesla Semi will be the world’s first long-range all-electric motorhome.

He said the motorhome build will only need minimal modification to the chassis of a Tesla Semi. The motorhome only requires the addition of composite structure onto the semi’s back.

The Tesla Semi will have a maximum tow weight of 36 metric tons (80,000 lbs.), which is more than adequate to tote a motorhome on the back. The truck’s enhanced Tesla Autopilot means the driver has more time to take in the scenery rather than worrying about the driving itself, according to Vanlifer.

Vanlifer is also taking Tesla Inc. at its word when the latter claims the Tesla Semi won’t break down for a million miles because it’s capable of running on two of its four motors. It’s also excited the Tesla Semi has a drag coefficient better than that of the Bugatti Chiron mid-engine two-seater sports car developed and manufactured by Bugatti Automobiles S.A.S.

“Our concept Tesla Semi-Home is a six-berth with a full kitchen, living space, toilet and all the other luxuries of high-end motorhomes and RVs (recreational vehicles),” said Jason H.

“The Tesla Semi with enhanced autopilot and a range of up to 500 miles on a single charge is very exciting. Here at Vanlifer, we see it as the future of electric motorhomes, campervans and RVs.”

Jason noted the Tesla Semi’s range of 500 miles (fully loaded) makes it ideal for motorhomes, “so you can clock up some big drive days without the accompanying gas-guzzling guilt.”

Vanlifer said the price tag of $180,000 for the 500-mile version of the Tesla Semi, isn’t that expensive for a large luxury motorhome.
