Tiffin for one advertises on their home page that the "Allegro Bus is "Favored by owners who live full time on the road".
That's not quite the same as "Tiffin recommends fulltime use". But I don't think Tiffin automatically voids the warranty for frequent or fulltime use. Or, at least they don't ask how much you use it.
The much-advertised Tiffin 5-Star warranty is NOT offered on all Tiffin coaches, only the upscale models. A Wayfarer, for example, gets pretty much industry standard 12/12 plus the Mercedes chassis 5 year warranty.
