My jumper cables are long enough to do that. However, the generator on an Interstate is tucked up underneath, between the spare tire and the rear axle, inside an enclosure, and it starts from the house batteries. Which you can't attach jumper cables to unless you disassemble the sofa to get at the battery box.
They do make a gizmo where you can just plug in a special jumper cable on a car without raising the hood. Forget what it's called, but my dad's shop truck back when he owned a service station had one. I may get one of those for the house batteries, so I can jump-start the generator by plugging jumper cables in by the rear bumper.
Interstates are the best Class B's on the market, but even the best class B is a collection of compromises all rolling in loose formation.
