Does the RV have double beds that retract up to ceiling? If so, like mine, I had to remove the upper bed and its brackets so the lower bed could touch the ceiling. As for total height, as the front enters it actually drops in height as it goes onto rv floor. Then, as more body goes up it gets tight on the 72 inch opening. I have a 2017 P1000-3, so the rear roll bar isn't there. With a P1000-5 you will have to shorten the last 2 feet of the roll bar. (at rear) Like one other reader said, try it before you buy it. As for pulling down suspension I decided it was too much work. In Nevada I unload every 50 miles to go on another trail, so I'd spend most of my day farting around with the suspension.
