No manuals. I found the engine manual online through Cummins and I found some bluebird manuals online, but no electrical yet. I'm not looking forward to figuring that part out.
It will be quite a while before I get any real mileage numbers. I drive it about 2 miles between the storage lot and my house with an occasional 10-20 mile drive down the freeway. I've only burned a 1/4 tank of fuel since I bought it in February. It won't go on any real trips until November at the earliest.
