Great write-up.
I also have the Leer 650 on my KR for about 3 months now. This is my first truck and after some research, I picked the Leer for the same reasons outlined above.
Love it with very little or no water seeping through in the rain.
Bought it at a local American Ladders & Scaffolds...
Have a (first truck) loaded KR Powerboost with > 1,100 miles and love it so far. Massaging seats (for the wife). Interior is all about preference, KR more country / ranch vs Platinum more “refined”. I live in CT but am a country / farm boy at heart (grew up in IA).
Happy with my choice.
