Generate an image of the back side of a pickup truck, transformed into a vibrant wedding getaway vehicle. The tailgate proudly displays a sign that reads "Hitched," surrounded by cascading ribbons in a bright and cheery color palette, with plenty of white accents to add freshness and elegance. Tin cans are attached to strings, ready to create a playful clatter as they drag behind the truck. Additional festive decorations such as colorful floral arrangements or balloons contribute to the joyful atmosphere. The image should exude positivity, excitement, and the promise of a blissful journey ahead for the newlywed couple.
