Think we have found it....Grand design Solitude 365 DEN

have you considered looking at toy haulers?
You don't have to use them for hauling "toys". The back room in most cases have electric drop down beds and lofts and tables and couches. The back ramp door of Jayco's Seismic converts to a large deck. You can get some that convert to a covered enclosed patio room.
There would be a ton of storage for full timing. Your bikes can ride in the back. Maybe you might even get a golf cart someday, easy to travel with.
