On the DT-generation Ram 1500 this is about as easy as truck maintenance gets. The arms lift and lock, the blade unhooks by sliding it down the arm's hook, and both sides come off in a couple of minutes with no tools at all in most cases. The only sizing detail that matters is that the two sides are different lengths: 22 inches on the driver side, 21 inches on the passenger side. Fit two 22s and the passenger blade will foul the A-pillar trim at the top of its sweep.
The mistake people make is letting a bare wiper arm spring back against the glass. The DT's arm springs are strong, and a metal tip on a cold windshield will chip or crack it — a folded towel on the glass costs nothing. The second most common mistake is not pulling the new blade up the hook until the latch actually clicks; if it only half-seats, it will fly off in rain at highway speed.

No differences: blade sizes, arm style and procedure are identical on the 3.6 Pentastar eTorque, 5.7 Hemi eTorque and 3.0 EcoDiesel, and across Quad Cab and Crew Cab. Only the optional wiper de-icer (heated glass at the park area) and rain-sensing wipers vary by trim, and neither changes the blades or the tools.

The 22 in driver / 21 in passenger sizing and the hook/latch attachment are correct for the DT Ram 1500 across all three engines, but confirm the adapter style against your own arm end before buying, since some replacement blades ship with multiple adapters.
22 inches on the driver side and 21 inches on the passenger side. They are not the same, so buy them individually or get a boxed pair sold specifically for the DT Ram 1500.
No. No DT pickup cab or bed configuration has a rear wiper, so you only ever buy two blades.
Turn the ignition to RUN, switch the wipers on, then turn the ignition off while the arms are mid-sweep. They stop out in the middle of the windshield, giving you room to work away from the hood lip.
Usually it is residue, not the blade. Clean the glass with ammonia-free glass cleaner, then wipe both the glass wipe path and the new rubber edge with isopropyl alcohol. Also check the blade is fully latched and the arm is not twisted so the rubber sits flat on the glass.
