Gas is cheap and works all of the time, but in my case, it would only be to fuel the stove and water heater. Plus I was a bit nervous as to the state of the gas lines under the house.
Guys are still ripping the bathroom apart, and it seems like the worst case scenario is coming true, plus a little extra... I was expecting to maybe have to replace the subfloor, some of the studs, and new drywall. Turns out under where the tub was located, the floor joists are severely rotted, the exterior wall that the tub was against is also badly damaged, along with minor damage in the interior walls. For the time being, I'm just going to throw down some cheap subfloor to seal up the room, and block off the doorway like I was planning to do, and just leave the room completely inaccessible and closed off to the rest of the house for the near future, until I can afford to get new siding, and do some considerable structure work. No more than a few months, but I need to keep working elsewhere and finish what I can. It was only going to be a closet anyway, so it's not a huge loss. Shouldn't require TOO much work. Replace 2 or 3 joists under where the tub was, which also happens to be the same joists I was thinking were rotted from a water leak in the next room over, maybe 8' away. Then rip the back wall out after bracing it, and frame up a new wall, which is only as long as a bath tub. Then frame in the new interior walls and cover with drywall, and it should be fine. A friend of mine has been a really good contractor for 30+ years, so I'll get him to come over and evaluate the situation, and see if any steps need to be taken other than what i have planned.
