Welcome Chief Mark!

Sam - Ill record the video but I don't recall our coach shifting that high (rpm), iirc I shift around 1300, maybe 1500 tops.

I'd love to be able to identify what ratios are in the trans.

Mark - I consistently see 9.9mpg at 70/72 mph...and I've never seen anything lower than low 8s. ONCE I achieved 13 running backroads (foggy night) between Atlanta & Destin...but I don't think I ever got over 55mph maybe 60 tops.

we are single rear axle similarly weighted to Sam - w/ the MBE4000 (DD13?) and the rear end is a 3.21





Am I correct in assuming all 12speeds have the same gearing?
Ours is an MO-16Z12A-A16...
