MPG problem and trouble shifting into gear and park

First question is my MPG. I have had this truck for nearly and year and have been getting 13 mpg. It is a late 99 F-250 extended cab with normal sized tires and everything stock. I had many problems with this truck and as I got it running better I figured the gas mileage would go up, but this has not occured. I drive pretty slow.

I have had the glowplugs all replaced. I had a injector cup replaced as well. New turbo pedestal, gpr, tranny flush. Replaced oil cooler gasket and flushed tranny. Several oil changes. New fuel filter and flushed that system as well. A friend has a standard tranny of this truck and says he gets 20 mpg!!

What can I do or is this about average. (I do have a plow hitch on this truck that I don't use. Could this give me a couple miles improvement if I cut it off?)

Second problem is that I have trouble getting this thing in to park sometimes. The nuetral safety selector thing causes the truck to seem dead when I turn the key and I have to jiggle the handle to get it fully in park. Also, sometimes I have trouble finding the drive gear. The tranny feels like it is in drive, but i have to kind of jiggle it to get it out of nuetral to drive.

Thanks all!!!!

Swap in a manual transmission, otherwise thats pretty common gas mileage.

Nonconformist. Functionality over bling.

My three rules for 7.3l troubleshooting: 1) Replace CPS and keep a spare. 2) Replace FPR and know your fuel pressure. 3) Hook it to a scanner and check for codes.
