Is the cab sheet metal? If so, getting that load coil above the cab will help a bit - especially with the tuning. Remember, with a well designed coil loaded antenna, the current is at its maximum and is fairly constant from the feed point through the end of the coil. If you have a big piece of sheet metal very near the coil, it is going to create capacitance in ways that you probably don't want.
