I would think something like a remote battery terminal attached, but wired directly to the starter hot terminal ( which should be bigger than the battery spade connector) with the ground attached to the chassis. Connect your clamps, turn your key. The remote terminal always attached, you could attached jumper cables when you have the generator in the back of a truck, etc. No need to lug around a loose 2x4.
Similar to what we do with the fleet truck Honda's. We wire them directly to the truck batteries.
