The all-new 2021 Ford F-150 will be arriving in dealerships nationwide very soon and rivals are already preparing. General Motors and Ram have been fighting over the No. 2 best-selling full-size truck sales slot for the past few years. The F-150, of course, has remained No. 1 for decades. That's not expected to change anytime soon, if ever, but the competition will never stop trying.

GM has begun authorizing hidden discounts for the Chevrolet Silverado 1500 and GMC Sierra 1500 that could tempt some shoppers without any brand loyalty.

CarsDirect did some digging and discovered both the Silverado Work Truck and Sierra Base, both 4x2 Regular Cabs, now qualify for a $2,000 so-called "package discount," just as long as buyers opt for the 4.3-liter V6 engine. This results in both trucks dropping below the $30,000 mark; $28,195 for the Silverado and $29,295 for the slightly more upscale Sierra.

The base 2021 F-150 XL 4x2 Regular Cab, to compare, carries an MSRP of $30,635. Chevy can now technically claim it sells the cheapest full-size truck in the country - and this new price doesn't even include any other incentives. Black Friday and additional end of year specials are bound to arise if they haven't already. But what's going on with the Ram 1500? It's not like FCA doesn't offer its own incentives.

Right now, Ram is offering regular buyers employee pricing on the 1500 for the entire month of November. The typically exclusive pricing program involves five percent below the dealer's invoice price and the total savings will therefore vary based on the chosen configuration. There is one catch, however. The employee discount can't be combined with the current 0 percent interest for 72 months offer.

But if you're on the hunt for a sub-$30k full-size pickup truck and don't have a particular brand in mind, now is a great time to make a purchase.
