Long story short the Ford F-150 has a drag coefficient of 0.59, the RAM has 0.56 ... while the Cybertruck prototype is at 0.39, but Musk said they'll probably reduce it to 0.35 (or even below that) on the production model.
So if Ford manages to get some EV technology that matches Tesla's (highly doubt it), their electric F-150 will be about ~30% less efficient. This inefficiency means they'll have to install a much larger battery pack, add weight and in the end will struggle to come close to Cybertruck's range.
Towing is a slightly different story, as the aerodynamics of trailers is not that great. The Cybertruck will have much better range when not towing, but add to it a huge brick of a trailer and the range will drop close to the F-150s', while towing the same brick.
EliTheComputerGuy would like to buy a plugin hybrid Ford F-150, which is a bad electric vehicle and a bad gas car ... so ... it may have more range with fuel than the electric trucks, but every other spec is far worse. DON'T DO IT!!!
I STRONGLY URGE PEOPLE NOT TO BUY FORD ELECTRIC VEHICLES, except maybe the Mustang Mach-E, which is an OK, sporty electric crossover. They offer 2x less value for the money, so only buy it if you're OK with that fact, otherwise buy a Tesla! (They cost between 35K USD and 100K USD)
The Tesla Model X Long Range Plus can tow a smaller Airstream trailer about 100 miles on one charge at highway speeds, so what the 70K USD Cybertruck will do is probably 200-250 miles with the same trailer. This is not bad at all, because Tesla's superchargers are only 150 miles (max) apart (in the US) and the Cybertruck's large battery pack (180-200kWh) will charge really fast, 80% in just 40 minutes while your have some food and stretch your legs.
