Two Pickups, but completely different in all significant aspects: model year, horsepower, starting price, and maximum occupancy. First of all, there is a notable difference in the starting price of the 2013 Ram 2500 Regular Cab, which is $4,145 less than the base MSRP of the 2021 Jeep Gladiator, which is eight model years newer. Also, the 2013 2500 Regular Cab has a more powerful engine than the 2021 Gladiator. And finally, the 2500 Regular Cab seats one more passenger than the Gladiator. Among similarities is the body structure.
