As has been stated already, get a portable charger to try and throw a surface charge on the battery just enough to maybe drive it the 40 ft to the charging area. The only catch to that is finding a portable charger the correct voltage, make sure it can do the voltage of the truck, anything else will not work.

But i do find it strange that if and when the truck was discharged enough why it wasnt taken to the charging station when going into lift interrupt mode? I tend to think if the truck is just "dead" that there may be some other issue besides just a dead battery.

I'd suggest calling the local service dealer and have them take a look and help with moving it. That would be a far safer thing to do than trying the "shadetree" approach dont you think?
Better to be safe than sorry i say :)
