OP,
A very impressive task...
Having said that we had a 05 RAM with a manual tranny that was used to pull large fertilizer tanks in the fields and large gooseneck cattle trailers in the pastures. This was our first manual tranny equiped truck for this application and although we didn't have problems with the tranny itself, it was our opinion the clutch wasn't going to live a long life. Now having said that getting heavy loads moving on pavement is a lot easier than soft plowed field or wet/soft pastures and you simply could not "let out the clutch".
