Less than three months after kicking off production of its flagship, solar-electric travel trailer called the Flow, electric mobility startup Pebble has begun deliveries to early customers in the US. The deliveries of these unique Pebble trailers will also include a new automated waste disposal feature called “Auto Dump,” a first for the industry.

Pebble remains a young electric recreational vehicle specialist whose latest milestone brings it closer than ever to shaking up a stale and derivative RV and travel trailer segment by using more modern and in a word, “cool” new technology.

This transition rides (no pun intended) on the success of its flagship trailer model, the Flow, which was unveiled to the public in the fall of 2023. At the time, we learned that the Flow trailer is 300% more aerodynamic than a conventional travel trailer, reducing drag and extending range.

Additionally, this solar electric travel trailer can be equipped with its own dual-motor active propulsion assist system, which helps it bear the brunt of its load while maximizing efficiency, regardless of whether an ICE or electric vehicle is towing it.

Before there was a solid timeline for deliveries, Pebble opened pre-orders for the Flow. This past January, Pebble unveiled a production-intent design featuring welcomed upgrades in space utilization and some genuinely remarkable functions—all controllable from a single tablet.

By April 2025, production of the Flow was underway at Pebble’s 60,000-square-foot manufacturing facility in Fremont, California, beginning with assemblies of an exclusive Founders Edition. Today, Pebble has hit a critical milestone in the production and sales process, kicking off Founder’s Edition Flow deliveries to its first customers.

The Flow’s arrival on the market, alongside similar, more sustainable recreation mobility products like Lightship, is helping ring in a new era of clean travel and tourism beyond the typical EV road trip. Pebble’s fully electric travel trailer enables its owners and guests to travel and relax off-grid for up to seven days at a time.

Unlike most traditional RVs and trailers, the Flow has its own propulsion system. It has also been integrated with advanced robotics and software-defined features to automate and ease the process of some of the most difficult and tedious parts of RVing, such as hitching to the towing vehicle. Per Pebble founder and CEO Bingrui Yang:

Delivering a Pebble Flow to our earliest customers and believers is a defining moment for our team. This product reflects years of engineering and thoughtful iteration, built on the belief that every detail, from setup to travel, should feel effortless and intuitive. This is the moment we’ve been building towards, and we can’t wait to see more and more Pebble Flow travel trailers on the road.

Deliveries of the new Pebble Flow travel trailer will also include another upgraded feature. The team calls it “Auto Dump” and hails it as “the RV industry’s first automated, one-touch waste disposal system.” It’s a well-established notion that waste dumping is the least glamorous and hygienic part of the RV experience, not to mention complicated, with multiple hoses creating a higher risk of mess.

Much like it has with several other functions of RV life, the Pebble team has reimagined waste disposal for the modern age, creating an automated “touch-less” process that consists of three steps:

• Placing the pre-connected hose in the sewer inlet (pictured above)
• Tap “Dump” on the Pebble App
• Return the hose to its integrated storage compartment

It’s a simple process indeed, but Pebble shared that much more is going on behind the scenes. In addition to an expanded black water tank capacity (18 gallons), the Founder’s Edition of the Pebble Flow features a macerating toilet, a pump-powered hose instead of gravity-based drainage, and built-in safety logic to avoid any user error while dumping (there is no “wrong lever” that could lead to spillage).

Pebble trailers that soon reach customer deliveries will also be capable of a self-cleaning rinse cycle, which uses gray water recycled from its sinks and showers, reducing overall water consumption and significantly increasing overall sustainability.

Founder’s Edition deliveries of the Flow are now underway, but Pebble said it will continue to scale its production throughout 2025 without risking product quality. More Founder’s Edition reservation holders will be invited to complete their orders in Q3. That model starts at an MSRP of $175,000 and is available to reserve with a $500 refundable deposit. Some customers may also qualify for a federal tax credit of up to $12,450.
