this is possible although not a professional/very safe method it will work in emergencies, positon the forks on the live truck together and put them under the counterweight of the dead truck (only the tips of the forks though!) then gently lift the back wheels off the ground and move forward, someone must be on the dead truck to apply the breaks in case they are needed, and proceed very carefully steering with the live truck. hope that made sense :)
