With a budget from $35 to $60 K you can buy some pretty nice units now due to a lot of folks having to sell. For example one dealer to check out is PPL Motorhomes in Houston, TX.

Instead of buying a 5th wheel and depending on the storage company to move it for you and being restricted to the Pismo area I would consider either a Class C or A. That way you could drive it yourself to wherever you wanted.
