Havasu
When I hear 'Havasu', I immediately think of Lake Havasu (AZ), which is
HOT. And although the RL is hot.....I am glad I am not driving a truck potentially named after an AZ city. (Sedona holds that honor with the Kia Sedona mini-van, which I almost bought several years ago

).
I can't find a dictionary meaning....
