FWIW I've also got a Stoplock Pro - my camper has the standard Highline MFSW and it fits with plenty enough space around it so I really don't think the OP will have a problem. The bonus is that the Pro has also recently come first in the an Auto Express test of steering wheel locks when it took over 5 minutes to crack: https://www.autoexpress.co.uk/accessories-tyres/95031/best-steering-wheel-lock
