I am contemplating buying a new truck before next season. It will be an F350 4x4 srw with a powerstroke. I have serious concerns with autos and high hp diesels. I like the new 6spd manual and thought that for the kind of plowing I do I would put an overdrive unit on it to let me shuttle shift between L and R and still have a faster plow gear, but still avoid a lot of hunting in the gear box. I would prefer to plow with an auto but I plow at most 10 storms a year in indiana, I drive the truck 365 and plan to keep it 5 plus years so I feel like in the long run i would enjoy the manual more and have better reliability, even if I have to change clutches more frequently. any thoughts on this I am 20 and have good knees. If that is a determining factor to anyone. please comment on personal exp. , reliability issues, and economics too but any thing you can tell me I will consider.
