Electronic titles when clear of liens are just like paper titles and are available to the buyer. When you bought the mh the seller I assume paid off his lien and the title at that point is free & clear.You can get a paper title to take to your state for registration in your name and recording your lien holder.
I don't know the details of your transactions but I would start with your lien holder acknowledging they have the title or waiting for you to get the AZ title put in your name with them as lien holder.
