What E-trailer does
E-Trailer B.V. is a Dutch IoT hardware company, founded in 2015 in Delft by Boy Trip and Rick Lenssen (now headquartered in Rijswijk), that builds a modular wireless sensor system for caravans and motorhomes. The architecture centres on an E-Connect hub wired into the vehicle's 12V power system, which aggregates data over Bluetooth from a portfolio of more than ten discrete sensor modules — including E-Pressure (tire pressure and temperature), E-Gaslevel (gas bottle fill), E-Waterlevel/Waterlevel XL (water tank depth), E-Load (hitch load, 2kg accuracy), E-Movement (intrusion), E-Switch (door/window contact), E-Temperature, E-Track&Trace (GPS), E-Level (digital levelling), E-Volt (battery monitoring), and the E-Suspension air-suspension controller co-developed with SMV — and forwards the data to a free iOS/Android smartphone app.
The business model is primarily retail hardware sales through bundling — Starter Package Basic, Starter Package Plus, and pre-configured Comfort/Security packages priced from €199.85 to €1,569 for E-Suspension — with individual modules priced €60-€290. An optional monthly subscription unlocks internet connectivity for remote monitoring and the Recovery alarm-centre integration. Go-to-market blends direct e-commerce, a 50+ dealer network in the Netherlands, German resellers (Obelink, Movera, Reimo, Camping-Kaufhaus, Campingplus), OEM factory integration with Hymer, Kabe, Hobby, Dethleffs, Sunlight and Trigano VDL (Sterckeman, Caravelair), and an annual presence at Caravan Salon Düsseldorf. CI-BUS compatibility enables factory installation.
E-Trailer operates as a private, profitable-scale-up style company in a niche vertical, with 11-50 employees and revenue that is not publicly disclosed. Itself disclosed as the customer-facing end-user market is the long tail of European caravan and motorhome owners whose vehicles have a 12V electrical system — a base the company claims as "nearly 100%" addressable across the existing European fleet. The value proposition targets real-time smartphone monitoring of safety-critical parameters (tire pressure, hitch load, intrusion) and comfort-critical parameters (gas, water, battery, level, temperature), with CI-BUS integration into OEM digital management systems increasingly the strategic wedge into new vehicles from the 2025-2026 model years onward.

Product offeringCore offering
E-Trailer develops, assembles in the Netherlands, and sells a modular wireless sensor system for caravans and motorhomes. The system centers on the E-Connect hub that connects to the vehicle's 12V power and pairs via Bluetooth and QR-code activation with a portfolio of sensor modules (tire pressure, gas level, water level, hitch load, motion, temperature, voltage, GPS tracking, and air suspension control), forwarding data to a proprietary iOS/Android smartphone application. Customers can buy individual modules, pre-configured starter packages (Basic or Plus), and optionally subscribe for internet connectivity and alarm-center monitoring.
Product overview
E-Trailer is a modular smart camping vehicle monitoring system developed and assembled in the Netherlands. The ecosystem consists of a core E-Connect/Starter Package hub that connects via Bluetooth to various wireless sensors and a smartphone app. The product portfolio includes two starter packages (Basic with E-Level, E-Volt and internet connection; Plus with additional E-Track&Trace GPS, security module support, and remote reading), plus 11 distinct sensor modules covering tire pressure (E-Pressure), gas level (E-Gaslevel), water level (E-Waterlevel/Waterlevel XL), temperature/humidity (E-Temperature), door/window contact (E-Switch), motion detection (E-Movement), hitch load (E-Load), vehicle leveling (E-Level), battery monitoring (E-Volt), GPS tracking (E-Track&Trace), and air suspension control (E-Suspension with SMV). The free E-Trailer app (iOS/Android) displays real-time sensor data and alerts. Optional subscriptions enable internet connectivity for remote monitoring. The system is CI-BUS compatible for factory integration and integrates with various motorhome manufacturer systems.

E-trailer competitors and assessment
Company assessmentDirect peers
- Thitronik: German manufacturer of wireless alarm, gas, and tracking systems for caravans and motorhomes. Most directly comparable to E-Trailer as an aftermarket smart-monitoring specialist competing for the same European RV owner base, with overlapping product lines in intrusion detection and GPS tracking.
Broad incumbents
- Dometic: Swedish global leader in RV appliances, climate systems, and onboard electronics. Overlaps with E-Trailer in RV monitoring and control systems; vastly larger scale and broader portfolio make it a broad incumbent rather than direct aftermarket competitor.
- Truma: German manufacturer of heating, air conditioning, and control systems for caravans and motorhomes. Comparable as an established RV electronics supplier with growing smart-control functionality (iNet system) that competes for the same OEM and dealer channels as E-Trailer.
- AL-KO Vehicle Technology: German trailer chassis and component manufacturer (part of DexKo Global) with a growing portfolio of electronic and safety accessories for caravans. Comparable as an OEM-tier trailer technology supplier with adjacent electronic product lines.
- BPW Bergische Achsen: German manufacturer of trailer axles, suspension, and brake systems with a telematics/connected-trailer offering (BPW AirSave, iC Plus). Comparable as a trailer-component incumbent adding diagnostics and connected-vehicle features that overlap with E-Trailer's monitoring value proposition.
- SAF-Holland: European trailer axle and component supplier with telematics and tire-pressure monitoring solutions (SAF Tire Pilot Plus, TrailerMaster). Comparable as a trailer-tier supplier expanding into smart-trailer monitoring services.
- Continental (VDO): Global automotive supplier with TPMS, telematics, and aftermarket diagnostic products (Continental VDO). Comparable in tire-pressure and vehicle-monitoring technology but operating across all vehicles rather than specializing in the caravan/RV niche.
- Hella (FORVIA): German automotive electronics and lighting supplier with TPMS and electronic accessory portfolio. Comparable as a broad automotive electronics incumbent that supplies trailer and RV OEMs with monitoring-related components.
