HaBO: Is that a Watch Fob in Your Pocket?

This HaBO comes from Samantha, who wants to find this historical romance:

I am hoping you can help me identify a historical romance novel I have been searching for over the past three years since I got back into reading romance.

Here are the details I recall:

– Genre: Historical romance, road trip theme, grumpy/sunshine trope.

– Publication Date: Definitely written before 2006, and likely before 2003.

– Hero: Gruff and aristocratic, though he has been away from his home for an extended period.

– Heroine: Lower class, possibly red-haired, and provides comic relief.

– Plot: A road trip romance where the MMC is taking the FMC back to his home, seemingly against her will.

– Specific Scene: There is a moment where the FMC says something to the effect of, “Is that a watch fob in your pocket?”—referring to his erection.

I thought I knew this one, but the watch fob and year didn’t match with my guess. Let’s HaBO!
