Today I'm at Premium Coach Group in Gilbert, Arizona, inspecting a 2008 Tiffin Allegro Bus. For me, I think these were as close to perfection in build and serviceability. Before everything got a bit too high tech and decor got too loud. But maybe I'm just old now. At any rate, obviously I'll look at the roof with you and then we'll peek inside. This is a gel-coat fiberglass roof of course using self-leveling silicone.
