Going into trucking with child-support and alimony payments

Curious if someone with child support and alimony payments can still make it as a trucker. I know you need a certain amount of disposable income on the road for meals, expenses, etc.

Right now I'm assessed $450/month, but I lost my warehouse job a few months back. (It takes six months to get a support modification done, meanwhile the payments continue to accrue). My present wife makes $10/hr teaching Head Start, and she's cool with me going on the road for long periods of time. But if I'll just be spinning my wheels with nothing to show for it at the end of the month, then why even try?

 

Yes, $450/month is my total assessment for both child-support and alimony---$250 for the alimony, and $200 CS for four kids, based upon my former income of $10/hr. It used to be $850/month ($600 for CS) when my income was $12/hr, but once I changed jobs and my income dropped, I had it modified. Now that I'm completely out of work I need to have it modified again, but the state Support Enforcement Division won't touch it until after six months. Meanwhile the payments continue to accrue mercilessly.

Just wondered if I would be able to make it on the road with such an obligation.
