Manufacturers or Models for full-timing.

I have been researching Class A's for when I retire to full time in. People have said that there are some built for full timing, but then don't say which ones. So, are there manufacturers or models that are built more full timing rather than just vacationing in? If, so please let me know. I want gas rather than a DP. I am not planning on traveling that much. Will be buying a used one.

It is just myself so I am thinking around a 35' would be fine for me. I live in Florida and plan on staying there, moving maybe every 3 months or so. Any recommendations?
