A half day of work and then it was off to Lowes. They didn't have the right kind of vinyl flooring so I ended up going to Home Depot too. I did get a nice window from Lowes though. I was able to get the big roll of vinyl stuffed into my parent's SUV with only a little bit of overhang.
We got it inside the mobile home and after all that my parents were still eager to start laying it out. It took a lot of shuffling because there isn't a lot of room to work but we managed to get it laid out. Next step, arrange the furniture in a useful way and tack down all the loose edges.
My parents were tired when they left and I am too. I sure hope they come back tomorrow. I still have drains and a window on my to-do list. The place is almost livable. Not quite but one step closer at least.
