This app could save you from voiding your insurance!
Towing a caravan is more than just hitching up and hitting the road, weight plays a large factor and is often fast forgotten. Something as accidental as overloading your caravan can result in you voiding your insurance without even realising. The Safe-Towing App allows you to calculate your on-road ball weight, allowing you to factor in full water tanks, generators, spare tyres, tool boxes or anything else that adds weight to your caravan. To avoid towing your van overloaded to a weighbridge and risking being illegal, the Safe-Towing App enables you to calculate your ball weight from the safety of your own home.
