1995 Blue Bird Off-Grid Skoolie Life | Cummins 8.3 + Allison 3060

This is a rare, fully built, off-grid skoolie powered by one of the most sought-after drivetrain combinations available: All Mechanical Cummins 8.3 diesel + Allison 3060 transmission.

Both the engine and transmission were replaced by a school district and have only ~70,000 miles on them. If you know buses, you know this is the combo everyone wants.
