I disagree...... especially if he uses Auto-Level but even with leveling manually.
I just went through a structural repair at Thor last fall on my 2020 Magnitude with the front cap. When it would go through the leveling process, it would flex enough that it started breaking screws around the front cap seam (because Thor uses screws that are too small, too short and too few in quantity).
You could put a level on the floor at the front, middle and rear of the coach after leveling and it would be dead center on. You could then walk outside and see gaps ariound the front cap seam that weren't there when the wheels were on the ground and the jacks were up.
The process of leveling provides enough flex that if the assembly wasn't absolutely perfect, it will expose wealnesses in the sealing of the coach allowing water to come makes it way into the coach.... even when perfectly level.
