Since 2010, SvTech has been offering free weight checks to motorhome and horsebox users across the UK, and has discovered that over 50% of those tested were running overweight, invalidating their insurance and thereby becoming a safety risk on the road.

The LDA Program

In an effort to promote greater awareness amongst road-users of the dangers of overloading, SvTech designed an application that allows an owner/operator to calculate their likely laden weight. This is calculated by the user entering the vehicle’s unladen weight and vehicle dimensions, and then adding their desired loads, e.g. bike rack, awning, water, fuel, passengers, unladen weight. The program then calculates the results, based on the data entered, to give a Load Distribution Analysis, and warning if the user has overloaded a particular axle or axles. The user will then know how much they are able to carry safely. SvTech can advise on any problems arising, as the company is able to increase the payload allowance on many makes and models.

What you’ll need :
– weigh vehicle on weighbridge to obtain front axle, back axle and overall weight.
– tape measure to measure front overhang, wheelbase, rear overhang

We are pleased to report ever-increasing usage of this program, which is designed for all users of motorhomes, horseboxes, vans and minibuses in an effort to improve vehicle safety.


Over recent years, SvTech has focussed its efforts on the motorhome market as DVSA announced that they believed 80% + were running overweight and that they were concentrating their enforcement teams in this area. We will continue to carry out similar exercises over the coming years at national Motorhome shows and across the motorhome, van, and horsebox dealer network.
