I see... I downloaded their brochure for the Gold Alfa and it says:
"Built on the Titan Structureâ„¢ frame, built in-house for the ultimate in quality
control and seamless integration with the chassis of the Alfa Gold fifth wheel,
this double-stacked, box-steel tube frame is designed for superior strength and
durability. The Alfa Gold is built for travel and the ultimate in comfort."
So I guess the frame is built by Lippert? DRV still gets Lippert build theirs so perhaps these guys are ok too. "double-stacked, box-steel tube frame" sounds decent to me.
Good to know that they are a step below the Lifestyle.
