EDIT NOTE: I did not include any of the rollable mishaps tables as that is not a simple copy\paste process from the VTT.
Here's a link for just the travel rules portion of what I'm working on. It is very rough and was directly copy/pasted from the Fantasy Grounds VTT module, so the tables are not formatted and there are ghosts of links from the Shadowdark books VTT version. I formated simpler things where I could for readability.
Here is a statement from the VTT module on why I am doing what I'm doing, lol. There are other adjustments I am making in the rules, but they are nowhere as extensive as my modifications to your work.
Why Adjust and Add More Rules?
While the combat rules are mostly sufficient for my tastes, there are a few areas where the ambiguity is a bit too much for my liking.
I'm not a fan of ambiguity, especially when multiple people are involved in a cooperative activity like RPGs. I prefer to have things spelled out to provide a clear baseline from which to start.
Additionally, some of the base rules and options don’t quite fit within the framework of the setting being developed here. The main purpose of this setting is to explore what humanity would do if it survived multiple apocalyptic events of a magical and otherworldly nature. To fully explore this world, I believe some adjustments and additional rules are necessary.
While I prefer well-defined rules, I also firmly believe that rules are meant to be broken when the circumstances require it. Feel free to incorporate as many of the changes provided here as you like, or ignore them entirely. It's your game, your group, and your friends. You know better than I do how you and your group enjoy playing an RPG. The ultimate goal is to have fun and immerse yourselves in a dangerous, alien world, far removed from our hopefully normal lives.
