The US doesn't have anything this spectacular. Unfortunately, I can't find any celebratory videos online- but here is a video of one of our mail trucks::

For larger packages, privately owned companies have larger vehicles such as this and bigger. One if the trucks in your video reminds me of a small Winnebago.
@lucifargundam Nice mail vehicle! いい車ですね!運転席の横に郵便物を置いておけばすぐ届けられる良いデザインだと思います。
郵便ではありませんが、日本でもこれに似たような車が今でも街中を走ってますよ。
