if you mean a smiley front, then i'm sure the swb isn't actuly very good for towing
i cant remember what the weight is, but i know when i had 1 i got old off by vosa officer for towing a trailer with it,
i only had a fiesta on the car trailer and the guy was convinsed i was over maximum weight,
i wasn't at a weigh bridge so wasn't charged,
tbh i still used it anyhow but you might want to bear that in mind
also i'm fairly sure it depends on whether your trailer is braked
