1993 international 4900
 

Just picked up a 93 4900 for about $3500!!! Just drove it back to my house it did pretty good the 100 milesack. Just want to know what mods can be done to improve fuel efficiency. Also im having trouble with the shifting I was told it was a 6+1. Is there a trick to the transmission? And what about cruise control? Any info/tips/tricks would be much appreciated.
