Ok MT, how would you handle this situation?re: layoffs

Like many of you I'm an oilfield hand planning for a possible layoff. As of today, I have about 4- 6 months of steady work then after that who knows.(Please don't ask what I do or who I work for it's not relevant). I would be considered a very late headcount reduction candidate. Trust me on that part.
My strategy is to plan every 14 days at work as being my last and stack cash in the process. The issue I have is this: I don't have a personal vehicle (my wife does have a van for kid transportation). I have a company truck with a gas card but I don't own a vehicle. My company allows us to use company trucks for personal use so I never even thought about. If everything truly goes to shite & the aforementioned 4-6 months turns into 3 weeks and then a slaughter occurs....well you get my dilemma.
The way I see it my options are this:
1) Approach my employer about purchasing the truck & use the car allowance to pay the note. I know some guys that have gotten great deals doing this. If I get laid off, I have a vehicle & hopefully a few months of payments saved.
2) Purchase a used vehicle now & continue to use the company truck. Find something really cheap, use it minimally, & begin paying it down now. If things turn around & I end up not needing it I can always sell it.
3) Do nothing, save as much as possible, & try to purchase something using cash should I get laid off.

Thoughts or suggestions would be appreciated. I hate going into debt as layoffs loom but I don't know if I have a choice. There is no way my wife & I could share her vehicle.
