Need a place to live and pay bills!

Hello,

I'm a divorced father with no place to live. I have back problems witch makes it hard to find good paying jobs. I do work full time at a low pay job. I have 2 kids that live with thier mom and i only get to see them on some weekends sense I don't have my own place for them to stay or visit with me. I'm looking to buy a R.V. to live in and pay off some debt iv encountered. I pay my child support but here recently its been about a month late. I get piad every 2 weeks and within 2-3 days I'm broke and still don't have all the bills piad. I do go hungry some days due to lack of money. I feel an R.V. is the best choice due to the rise of rent, utilities and my job. Please any help will be gratefully appreciated!
