Pebble Flow EV Travel Trailer: Glamping Goes Electric

One of the great joys of camping is the silence. There’s nothing worse than getting out into the wilderness, away from society, and then hearing somebody one campsite over start up a loud, smelly gas generator.

Pebble, a California-based company that is building a new travel trailer, is hoping that an electric RV is just the thing to bring some quiet to the glamping life.

The Pebble Flow is a travel trailer with a big ol’ battery in its floor. It can run the lights, shower, heating, and air-conditioning, and anything else you might want to use power for out in the woods. The battery also powers a towing assist feature, so the Flow can give itself an extra push when you tow it down the road, easing the burden on the vehicle you’re using to haul the camper.

Pebble first announced the Flow in 2023, but it hasn’t revealed the full array of features it is planning to put in the camper until today. In an announcement timed for the week of CES, Pebble says it will assemble and deliver its first campers in the first half of 2025. They are available for preorder now, starting at $109,000, but going up to $135,500 if you want to be able to control its features with a companion mobile app.

In the Flow

The Flow has the same aesthetic as many current-model EVs, with big windows and soft, curved features that aim to make it more aerodynamic. It looks like a futuristic luxury spaceship, or a really big fancy toaster, depending on how romantic you want to be about it. CEO Bingrui Yang is very romantic about it: He chose the name Pebble for the company because the naturally occurring smooth stones tend to bring people joy, and he wants the electrified camper to foster that same feeling of serenity.

I got the chance to wander the tight space of a Pebble Flow demo unit at Pebble’s headquarters in Fremont, California. It holds just about everything you’d want if you’re out RV’ing. Inside is a kitchen with an induction stove, convection oven, sink, microwave, and refrigerator. The cabinets have ample storage, and there are concealed hatches in the floor for more storage. Most of the windows pop open if you need to let in the breeze. In the back rests a queen-size Murphy bed that retracts into the wall to make space. A dining table can be broken down into a second bed at the other end of the trailer. A bathroom and shower sit right in the middle of the floorplan. A glass wall separates it from the rest of the interior, but the person in the bathroom can press a button to electronically frost the glass if they need a private poo.

For the experienced RV enthusiast, this probably all seems like standard fare for a trailer that costs over a hundred grand. Well, you’re right, but what Pebble is hoping is that its EV-like add-ons make the Flow special.

The Flow is powered by a 45-kWh lithium-ion battery built into the floor of the camper. That’s slightly smaller than the batteries built into compact EVs currently on the market, and about half the size of the auto industry’s largest EV batteries. Pebble says the battery can power the interior systems for up to seven days on a full charge. A set of 1-kW solar panels built into the roof can juice the battery part of the way back up while you’re on the road, and regenerative charging kicks in during towing. It has vehicle-to-load tech as well, so you can connect to the Flow to use it as a backup power source or EV charger.

The Pebble Flow is not actually an E-RV in the sense that it can function as a vehicle on its own. You’ll need another rig to tow it anywhere. Pebble says that while towing with a hybrid or gas engine vehicle is probably going to get you farther, you can tow it with another EV. The 25-foot trailer weighs 6,200 pounds loaded up with all the options, so it will take some muscle to move it. The Pebble website does show the Flow being towed by a Cybertruck. (While I was at the company’s headquarters, I noticed a matte black Cybertruck in the parking lot. It belongs to Pebble’s CTO, who talked about it a lot while I was there.)

The powered towing assist feature can be toggled on when the Flow is in motion. While the motors provide a decent push behind a real vehicle, they are just powerful enough to roll the Flow around a little using a smartphone app, though it only moves about 1 mile per hour on its own. That is enough to spin it in a very slow circle, but not anywhere near enough to get you down the block. What it does let you do is maneuver the trailer into place at the campsite without having to push and drag it around with your car. Just unhitch the Flow, grab your iPad, and steer it like a giant, slow RC car into the perfect spot. Engaging the tow-assist mode or driving it around the campsite will definitely reduce the trailer’s battery life for actual camping activities, as you can imagine.

Pebble has a feature it calls Magic Hitch (it’s not actually magic) that lets you use the app to hook the Flow up to the trailer hitch on your towing vehicle. Just guide it in with the controls on the screen, and when the Flow is close enough, hold a button and the hitch will use its attached camera to find the exact spot to hook on. Another feature, called InstaCamp, lets you park the trailer on an uneven surface and then press a button to have the camper level itself automatically.
