RIALTA
After looking around a bit I think this fits the bill for (near) current production of an aero motorhome. Others (older) would also include Winnebago LESHARO and Itasca PHASER.
Motorhomes have a high cents-per-mile cost, so older & cheaper is not necessarily a bargain when repairs start to mount. I haven't looked into the problems with RIALTA at any depth, but were I looking to cover 10-20,000 miles annually I think this would be a good start given it's limitations.

For brand new (and longest life in this instance) I'd stick with a motorhome based on the
Sprinter.
This is but one example:
ERA | FREEDOM. FLEXIBILITY. FUN.
Expediters average at 20 or above using these vans in commercial service, with good records, overall.
