Thank you! I think the dimension change makes more sense now:
- The original heights didn't include the roof vent, even though it was standard.
- The extra height is partially due to the larger tires and higher axle.
- The extra height is partially due to including the A/C and TV antenna.
- Only 6" is subtracted without A/C and TV antenna because there are still items (like the roof vent) on top.
And:
- The original widths didn't include the awning or the running lights.
- The new widths do include these, and removing the awning only saves 2" because the running lights are the other 2".
So the actual dimensions of identically configured models haven't changed appreciably, except maybe a bit due to the increased tire size and axle height. Any of the larger models should still (barely) fit through a garage door that is 8' wide.
