Truck first aid kit

Recently purchased a new truck and I’m looking into a quality first aid kit to keep in it at all times, currently I’m looking at MyMedic MyFAK standard (169.95 on Amazon) and I have a few questions 1 is this a decent kit, everything I’ve seen online about it makes it seem good but I’m curious is there anything better around the same price range 2 would you go with the red bag that all first aid kits are or go with a more stealth approach (bag will be stored under my rear seats) 3 would you add anything to a kit that size other than a CAT tourniquet? Thanks in advance
