Hi, The MSRP I paid through Specialized was actually a bit cheaper than an LBS authorized dealer because Specialized picked up the tab for road sticker registration.
HUGE difference between 5.0 and 4.0!
FutureShock + Carbon Fork
12 speed vs 10 speed
Deore XT vs Deore Shifter and Derailleur
Higher grade cassette
Shimano Chain
Carbon seatpost (EQ only)
Better rims
Higher spec Tektro brakes
Higher spec headlight
Higher spec saddle
5 cassette is 10-45t vs 4 cassette at 11-42t. 5 is faster by a bit and a bit more torque on a given grade at a given cadence. Doesn’t seem like a huge difference until you’re passing up a rider on a 4
In my opinion it’s an entirely different bike and great value. You can compare side by side on the website:

There is a detailed document describing max loads on the bike, also one specific to child carriers. I will look today. Note the carrier is a bit special because it’s integrated with the fenders on the EQ version. I’m not sure you’d need to change the rack though - it’s racktime compatible btw. Also rear wheel cargo limit is 55lbs/25kg.
Update:
@aj1 - OK I had a look at the child seat addendum. Basically it’s a few warnings and disclaimers saying legally the bike was designed for one person and you assume all the risk. Also apparently the carrier/rear rack can carry 25 kg max rated. So really it’s just a matter of how you would go about mounting the child carrier.
