The RoF Ultimate Mods Pack has some of the same mods you will find in RoF Refined, but also includes 18 additional mods. Also, some of the mods with the same or a similar name to those found in RoF Refined are actually different mods that I prefer, such as the Reduced Oil Splatter mod which has darker oil and blurs your vision less than the version found in RoF Refined.
The Mods are zipped up "a la carte" so you can pick and choose the ones you like. They are all JSGME ready.
Enjoy!

While you'll still have plenty of nice days in RoF with this mod pack, here are a few examples of the more foreboding weather you'll also see using the "Heavy Clouds" mod included in this pack. The "More Ground Detail" mod (also included in this pack) is also very apparent in these screen shots:
