T@B 360 External Height

I need to know the height so I can modify my garage and garage door to park it there. I’ve sent inquiries to 2 dealers and to nuCamp, with no responses as of today. I watched Mandy’s 360 tour video where she said the height was 8’9”. Not sure if that is a measurement to the top of fan cover, to the top of shower vent or just to the top of black trim, or where she got that number. (Also, she said and nuCamp site says listed values are subject to revision) So, as a possible math problem - if we know the height of the chassis/axle Boondock version; 14” wheels; the heights of existing 320 and 400 models; the difference in inside heights between 320 and 360; the inside height of the 400. By math and deduction, can the external height of the new 360 be calculated? Any responses would be much appreciated. //Thanks.
