Rob,
Thank you. The 5.45 puts me right on the edge of a good overall low gear with the turned around over drive. The 5.45 with 9.27 low of turned around double over drive gives me 50.6 overall reduction in low gear which is much better than 36.5 overall with the BDSL-181. I read that the loggers like 60 overall ratio so that is kind of my target but maybe 50.6 is still ok for small dump truck and the turned around double over gives me a good road gear at 0.64 over drive. But if I leave the trans like it is I would have two good low gears (low and first) and maybe a decent road gear at 0.87 over drive. Truck would top out around 67 mph and 55 mph should be about 2100 rpm. I probably won't get more than 25 or thirty miles away from the farm so maybe leave the 13 alone is the best answer.
