Looking to replace family/work truck

We're a family that lives in East Texas and I lost my job in the past month. I didn't realize I had a suspended license until after being pulled over for a front license plate. I unfortunately lost my job, which is of my own fault. I have been late to change he address on my licence so they sent the info about it to a prior address. We have two kids, one each from a prior relationship on both sides. So moving isn't an option for us do to distance from children. I'm an RVDA certified technician who decided it would be best to work for myself. So money would be come less of a problem. I've started a mobile service company, and currently use my 2003 Dodge Ram 2500 diesel truck with over 260+ as a work and family vehicle. It is very illogical for both. I have found several Chevy trucks that would be cheap to maintain and affordable. As well as quiter and with decent room for two small kids. I am able bodied and I can still and do work. It would take me a long time to keep a new buisness aflot, thankfully being in the trade I already own the tools. On top of getting a manageable vehicle for my family and myself. If that seems like alot of information, I appolgize. I'm a Texas dad we dont really know how to ask for help. But we'll try. Thank yall.
