Just brought home our 2009 Bluebird Vision. It has a Cummings ISB 200 and an Allison 2500 transmission. Only 109,000 miles. It made the 150 mile trip home with no problems, except the front A/C didn't work and it was 108° outside. Plan on using the bus on short visits to the lake and perhaps one 5-6 day trip per year.
