Registering a Teardrop

Are there any Illinois tear droppers out there who have built their own. If so, I need help. I went to register my camper last week and ran into all kinds of bureauacracy. they can't seem to figure how to register it! they wanted all kinds of info, size, weight, pictures of all angles, a detailed drawing of the frame, etc. they told me it may take up to several months for them to get this right. Huh? anyone else ran into this mess? thanks
