i haven't read all the responses to the original poster's questions so i don't know if this has already been said, but i do know for a fact that harris county sheriff won't sign off on class3. i'm lucky to be in travis county now but back when i was in harris i already heard that it was damn near impossible. recently at a class 3 store in austin i heard more people complaining about harris county's sheriff not signing anything. that trustee/personal enterprise thing is a way around it i think, but i don't know how it works. probably should visit a houston class 3 dealer and get the know how. good luck!
