New truck time

I have the battery pack ac system. I tried it when the truck was new. Then when I needed it the battery's were dead. The dealers I have been to never could fix it so I gave up. It didn't come with a manual . So I don't have much to work with.

 

There were some calibration issues on the MF11s not too long ago. They seem to have been cleared up with the last flashes, but I think I would still prefer the 13. How fast are you interested in running? You can run upper 60s with a 435hp MF13, 3.25 or 3.36 ring and pinion, and a low pro 22.5 and still get over 7 mpg pretty easily at close to 80,000. A direct drive trans/2.64/low pro 22.5 combo will get you near 8 with a 410hp MF13 if you keep the road speed down in the low 60s and are running less weight
The battery powered APU works ok if you are running a mid/flat roof 56" sleeper, but it struggles with the 73" hi rise or condo sleepers.
Let me know if you have any other questions or need a set of specs.

Kansas. I would spec a MF13 430MT, Gear it @ 3.21 use, all arrow package, single axle w/ pusher, and progressive shift. You should limit your cruise and and ped to 65mph. Also, gear down protection is a nice option. You will be 10 + mpg. We are seeing 11 mpg in a lot of cases with light highway loads.

 

you dont want Gear down protection and progressive shift programmed together. Its one or the other. They conflict each other and cause low power complaints.

 

Those with the MF 13 Engine, what is the optimum RPM for both performance and economy? Speed is not what I am looking for, just best RPM for that engine.
