Having embraced heresy (GURPS 4e), I use the write-up in 4e's Ultra-Tech
as it has a 'wheeled ATV' that is suspiciously like a good old Traveller
wheeled ATV. I uses two large (200 lb) powercells to power everything
including the eight wheels, each with their own electric motor. It has a
solar power array as backup, which is noted as being able to power
everything except the motors. Presumably if you left everything turned
off the solar array could slowly recharge the powercells, and in a
developed area you'd just plug in for a recharge or yank the cells out
and swap them.
