It's an interesting thought experiment, and people who do long-distance towing (and probably overlanding) and such would absolutely love switching to gas/diesel.
BUT, some of these claims are... questionable.
Half the weight: The base Lightning is only 10% heavier than the most similar gas truck as far as power/features (Powerboost) - 5500lb vs 6000lb. Comparing apples-to-apples trucks, none are half the weight.
Half the price: The base 2024 Lightning (Supercrew 4x4) is $55k, and has a $7500 tax credit available, resulting in an effective $47,500 price. The absolute cheapest, zero option, weakest engine 2024 F-150 Supercrew 4x4 is $47k.
So, half the weight and half the price make for a funnier meme, but not really accurate in most cases.
