Great idea. Maybe add a column for the controller model? Would you like community input on the various years/models from those who own them? ---

Thanks, nice reference. 2000-2001: e825, 3.5hp, 8.9 gears. drum brakes, schott charger, T1 controller. Steering, battery and suspension are the same as the 2002-2004. Not sure precisely when change from Schott charger happened, if it was when the 02 model year started or in late 01. 2002-2004 are e825 also - number of seats was by the name following the model. “longback” truck had different rear suspension of 2 coil overs per side Do you recall when the front suspension changed?
