For class A's not recently by the manufactures, a third party or required by the government. Winnebago did some testing 30 years ago or so and there's also the Wonderlodge roll over testing from around the same time but little if any since.
And due to the average class A weighing in excess of 8K Lbs most of the state or federal DOT regulations for a lot of the latest's safety devices (stability control, adaptive cruise, rear camera, driver/passenger airbags, antitheft and such) don't apply. Seat belts, safety glass and a few other items are about it.
You do have one big gain over the average daily driver, your ankles are probably higher than their roof line of most vehicles on the road. Get hit by something smaller and they go under your seat and into the chassis. Blow a steer tire at 65MPH and all bets are off regarding a good outcome.
