Regained enough energy to watch Duze's Sweden bike packing ride.  It inspired lions to ponder a cross country version of heroine truck.  This version would be 3x longer than the existing truck, slightly taller & wider.  It might be a dogsled with wheels.  It would have 60W of solar generation on top.  It would have 2 scooter traction motors & 2 front steering wheels.  It would have a rear handle bar for manual pushing.  It would need some minimal off road capability.

The motors could reconfigure for dynamo mode to recharge.  It could also recharge from manes. 

It would have the existing leash mode & RC mode with heading hold.  It would have dual RC transmitters.  For dynamo recharging, it would have a manually pushed or pulled mode with heading hold.  It could have a variable resistance mode where the motors provide a configurable amount of power in addition to animal power.  This would go all the way down to full dynamo mode.  The variable resistance & manual traction modes would require a robust leash design capable of transferring loads.  The fully extended leash would transfer the load or there would be a second cable parallel with the leash.  Leash traction mode might provide the off road capability.

In the worst case, it would have shopping cart mode with no electrical needs & no steering linkages.  Not sure if this would require reconfiguring the front into castor wheels or using handle bars.

Then, there's no practical way to really use it.  Lions could remotely imagine driving it to Tracy & Yosemite on test runs.  Lions can't take many days off to do such a run.  The shortest destination justifying it would be Martinez.  

The problem with Duze & Sweden having 5 weeks off every year is they're part of NATO.  Someone else on the other side of NATO has to work 52 weeks/year to pay for the military that allows Sweden to have 5 weeks off.
