I bought an 03 Ranger 4x4 with the 4.0 liter, as my personal and work truck. My trailer is a 5x10 all metal with the mesh floor. It is very light compared to most trailers, and all I will have on it is on WB, a 21 in. blowers, and edgers/trimmers. Do I need to put the truck in overdrive, or drive for transporting my trailer. Also is it ok for it to put it in drive while accelerating then shift it to over drive once I get up to about 55. The gas mileage is worse in Drive, but if it saves the trans it is worth it. Thanks for the help.
