E-Trailer has developed the E-Load module especially for caravans to determine the bearing load. It sits in a specially supplied jockey wheel that is mounted on the drawbar in place of the old jockey wheel. You only have to enter the distance of the new jockey wheel to the ball coupling and the distance to the axle of the caravan. Based on these parameters and the weight currently on the jockey wheel, the sensor then determines the exact bearing load on the trailer coupling.
Smart caravaning for caravans and motorhomes with the E-Trailer app!
With the E-Trailer app and retrofittable sensors, caravan and motorhome owners can monitor the status of their vehicles at any time using their smartphone.
The E-Trailer system consists of a central base station, dedicated sensor modules and the smartphone app. Only the base station needs to be connected to the recreational vehicle's 12 V electrical system; all other modules communicate with it wirelessly.
An internet subscription is required for E-Track&Trace and internet-based remote monitoring. Subscriptions start at €70 per year and can be purchased directly through the E-Trailer app.
