The new update may not be all that huge, but it's a blast. (And makes me want to look into Snowrunner.)
I love loading up all the trash, carefully driving it to the dump, and then getting to play garbage disposal basketball. Very chill and fun.
I haven't even started the expedition yet! Just dump trucking on our main save.

I'll also add that I had issues with inventory space because I stupidly accepted the Collection of Decorative Bones reward and could not find anywhere to sell things. Road Trip IV rewards you with a Pre-Packaged Trade Rocket Unit. :)
This expedition taught me not to blindly accept rewards. I lost a couple of hours because I was trying to find a trade terminal.
