Bent axle.
Bought a 2019 Imagine brand new, a 2600 RB, weigh around 7000 lbs dry. First long trip, springs gave out, went flat, Grand Design replaced those under warranty, next was the rear axle bent. Turns out,...

Yes, please report back on the findings. Very curious about this. 1/2" toe out, wow...
When looking at the frame behind the rear hangers, look for this. This is in the advanced stages after the frame ratcheted itself down over time, but this lower flange bend is what started my issues after that pothole interstate.
I reinforced the hangers and the lower flange on the outside long ago to remove the I-beam web cracks that can happen with this setup. Mine web never cracked, as I was proactive in reinforcing it. The outside reinforcement helped the outside part of the lower flange resist the deflection, but the inside with where the larger issue started.
The outside of the left rear hanger. The slide room is just above this hanger.
The left rear hanger area inside the frame shows a distorted lower flange. This is a problem if yous have any deflection in this area. Put a straight edge on the lower flange and see if it is straight.
Using a straight edge across the area
This amount of bump is a problem that will get worse under normal towing in the future.
I hope this helps and you do not have this bent lower flange issue. Bending that heavy axle toed out that far, something big happened or lots of little to medium hits.
