Since there are no custom fit hitches for your 2006 Bluebird All American FE School Bus you will need to use a universal hitch. I recommend one of the following:
-Draw-Tite Ultra Frame Service Body Trailer Hitch Receiver # 41990-07 (7" brackets)
-Draw-Tite Ultra Frame Service Body Trailer Hitch Receiver # 41990-16 (16" brackets)
The only difference between the 2 is the size of the mounting brackets. Both have a 2" receiver and the same 16,000 lb max trailer capacity fitting frames up... view full answer...
