You will hear both good and bad but this is my take. I have a 1998 Winnebago Luxor with this set up that I have had near 20 years, it has never failed. And after 2 Monacoes with roof a/c there is no comparison. The basement a/c will freeze you on the hottest days, a limb will not knock it off the roof, and it pulls right out for service. I use this unit for my drag racing and sometimes it runs 4 or 5 days without ever being turned off. Gen has 4000+ hours so the a/c is near that. Also neither of the Monacoes had as much storage as the Luxor so put that myth to sleep also. That's my take.
