I am majorly upside down with my suburban and have bad credit...any ideas?

[mlholley1]

I traded my minivan a little over a year ago for a suburban, I was upside down with the van, so it got tacked onto the suburban. I owe about 25K on the whole loan. I'd like some advice as to whether I should let the bank repo the suburban, and then try to find another minivan for a few K, or keep it even though the gas and payments are murder, but it's the only good thing on my credit. Every other aspect of my credit is shot, as in below 500, are there any other options for me? My family has to have a large vehicle, we have five kids. Thanks.
