Can you use your American DL in Thailand?

You can use your foreign drivers license in conjunction with an international drivers license for a brief period of time but eventually you need to get a Thai drivers license, if you plan to stay for a while.  A Thai drivers license is also a very convenient form of identification for most purposes and easier for most people to deal with than a passport.
