There are lots o good suggestions here. Here are my thoughts:
Texas may be OK for Winter Season in terms of marketing in a warm climate, but you simply can't beat Florida. Many more snowbirds come here and while campgrounds are packed, lots of folks are out shopping for RV's. There is the AlumaFlamingo show (https://www.facebook.com/Alumaflamingo
) which attracts many more and its a great place to put yours up for sale while camping, and there are some Dealers at the show that will assist you in listing it.
Then there is the RV Supershow in Tampa which is a good place to chat with dealers. There are also several dealers that I have spoken to at that show that do not carry AS trailers, but love to have used ones on their lots (some only carry Interstates, or none at all).
Lastly, some of the Airports have covered parking available on short and long term for storing RVs. If someone from out of state wants to see it, you can easily meet them there for a tour (offer to buy them a ticket if you think they are serious.). I have my RT van stored at a Wally Park @ JAX, but I used to store my AS there as well. Many snowbirds do this instead of driving all the way home and back.
That's my 2 cents worth.
