Same brand, same dual-fuel dial, one real question: does the furnace and well pump make the backup list? The 7,500W unit powers a home's essential circuits through a transfer switch; the 3,500W unit runs cords to the fridge and lights. The $500-ish gap buys the 240V outlet, electric start, and double the wattage — worth it the first time the heat stays on.

Pick the Champion if…

✓You'll ever want a transfer-switch hookup
✓Electric start matters on cold mornings
✓Well pump, furnace, or 240V anything

Pick the Champion if…

✓Cord-based fridge/lights backup is the whole mission
✓Smallest credible outlay for outage insurance
✓RV trips are the more frequent use
