Tammy, there are a few things I can let you know about, that your Chapter 13 office obviously has not informed you of. Let me first say that I'm in North Carolina (work for a Trustee in NC), and there are some things that can be different depending on the state you are in, but the majority of things I can tell you will be across the board regarding Chapter 13 cases.
What you are saying about your attorney is VERY common. I don't know why this is the case so much, but not all attorneys are like that. I have however, run across many attorneys that just take the money, file your papers, and let the case run its course.
About your truck, unless you are dismissed from Chapter 13, the company has no legal right to take the truck. In fact, they can't take it while you are IN Chapter 13. They can only reposess the truck if your case has been dismissed. Sounds like your attorney should have been more precise with his information to you.
You can get another attorney and switch, but you may have to pay your new attorney the full fee to file Chapter 13 again.
I will say that an attorney can be very helpful in your case, but not necessary. The majority of our cases of debtors that file pro se get dismissed although. You should probably just stick it out with your current attorney, but try to work with the Trustee's office as much as you can. If you miss a month's payment or two is when the dismissal motion will be filed, and you and your attorney are always informed, but if you make a full court ordered payment prior to the dismissal hearing, your case will remain in Chapter 13. The only catch is, that your payments will be increased to cure any arrearages you created when you missed payments. This is necessary, because if the plan is not caught back up, the creditors in your case can file a motion to have you dismissed from Chapter 13.
I hope this helps some.
