Damnit man! Just caught this today (haven't been on here much lately). You did the right thing!
I had initially planned to do my door notches that way but decided to go the other way so I can run full trim. Trim would look weird stopping 2.5" before the wheelwell...
The frame: great f'n idea! With a step notch it won't matter and fewer floor mods. You'll still need a DS tunnel though.
Proportions: I do like the shorter rear from what I can tell, but as Hart_Rod said would like to see some wider shots of the whole thing.
Top: Love it! You did the opposite of what I did. I raised the rear to match the front, you lowered the front to match the rear. Looks awesome. Personally I like the bubble-top look too.
We get enough of these built and we can have a Tahoe meet in Tahoe one day
Can't wait to see more!
