Chocka: Caravan Checklist

Which wheel goes on the ramp, and how high? Lay your phone on the floor and Chocka answers for every wheel: front left 9 cm on step 3, front right 6 cm on step 2, rear left 3 cm on step 1, rear right stays. It works from your own wheelbase and track and the steps of your own levelling ramps, and tells you how level the van will sit once it’s on them. The bubble sits in the middle of your van, so you can see which way it leans. CARAVANS TOO Two wheels and a jockey wheel: which side goes on the ramp, and how far to wind the jockey wheel up or down, worked out together so the second adjustment doesn’t undo the first. Single or twin axle. HOLD IT, THEN WALK OUTSIDE Freeze the reading and take it to the wheel. A firm tap tells you when the van comes level. CALIBRATE IN 20 SECONDS Two readings, one each way round, on any flat surface. Every phone’s tilt sensor is a little off; this cancels it out. LEAVE NOTHING ON THE PITCH Leaving, arriving and packing lists that know what you drive. A motorhome gets the step, the roof vents, the TV aerial and the hook-up cable. A caravan gets the coupling, the breakaway cable, the road-lights plug and light check, the jockey wheel and the corner steadies. Safety items are flagged, and if one is still open when everything else is ticked, Chocka names it. YOUR VAN, REMEMBERED Your tyre pressures show inside the tyre item. Add, rename, reorder and flag items. New trip unticks the list and keeps your changes. Several vehicles, each with its own lists. PAYLOAD CHECK Maximum and weighed mass, plus people, water, gas and luggage: how much you can still load, or how far over you are. Centimetres or inches, bar or psi. English, German, Dutch and French. No account, no subscription, no ads. Your lists stay on your phone, and it works where there’s no signal. One payment.
