Anyone know who could move a large park model from WI to AZ?

There are several RV towing companies in Elkhart, IN that you can call and ask. Last I checked it was $2/mile to tow. They contract with contractors to tow RVs all the time and can likely help you especially since the winter season is approaching and they won't be too busy here in a couple weeks. Though right now weather is good there sort of. Not freezing anyway.

There are volunteers that tow RVs for $1/mile or even less, like free, if it's a compassionate move. You'll find them by googling or by checking with Escapees.
