As has been said, that Cameo is a really nice fiver - I would love to have one. You can have an aftermarket auto-leveling system - and probably a number of other options - installed for a lot less than the hit you'll take on trading for a DP (not to mention the depreciation if you buy a new DP). I'm in my mid-60s and don't have auto-leveling, but we find that Andersen levelers and a Blue-Tooth leveling device that transmits to my phone make leveling very easy.
Now, on the other hand, a DP with a tow'd is a very nice combo if you move every few days. I've seen a number of Escapees that have "aged out" of the moving lifestyle, kept their DP and tow'd, and settled down in the DP in one of the Escapees co-op parks. While they're able, they still take the motorhome out for trips... it's just not full-time traveling any more.
I had a political science professor once that said that the definition of politics is determining what is valuable and who gets it. You just have to decide what is most valuable to you and who gets your money (you or a dealership).
