Keystone's answer today:
"Thank you for contacting Keystone RV. I did review with my manager, and my manager reviewed with the general manager, we are not going to be participating on any modification to our units, you can most definitely install an extra escape window but it would be at your cost, it can also affect your warranty in the future. However, Keystone RV will not participate in any modifications."
I'll be following up with RVIA and NHTSA next, I guess. The question of whether the RV meets the standard still has not been answered. First they tried to answer the question by pointing out the lack of a door on the bunkhouse means they believed they were still in compliance. But when I pointed out the door to the bedroom is still between the bunkhouse and the fire escape, they dropped the question of compliance altogether and just said "No." It seems like Keystone is trying to sidestep the whole question.
