Any recommendations for roof boxes apart from Thule which are double the UK price here. Looked at KK roof racks: https://www.facebook.com/@kkroofrack/
Prices reasonable but the volumes they quote appear to be very inaccurate. Eg 740 litre box (11,690 THB), dimensions, 190 x 85 x 36 which as a simple rectangular box = 580 litres, so I cannot see how they can promise 740 litres
