Yes - park models are technically still 'able' to travel in AZ they must still have axels and wheel hubs attached and the hitch available to be re-installed.
And some TT manufacturers market some of their trailers as "park models'.
However the number of snow birds who spend the winters in park models is ever growing ( in our park in Mesa they have sold over 100 new pms in the last year!!).
The demand for a separate thread will only grow but will only happen if those of us who use pms keep requesting one.
Lets do it!!
