European fire trucks have all the same equipment but are smaller - they just pack better. Sometimes it does take longer for European fire-fighters to get set up due to unpacking. The reason is partially regulations, partially culture. US have to have engines that are powerful enough to pump like 1.5x the needed water for a fire hydrant.
US fire trucks are custom chassis, European they just modify existing truck. Furthermore they have a lot of smaller vehicles for EMS rescue, I think only like 4% of what a fire truck responds to is fires, most are medical or service. None of this is the fault of the actual firefighters though 🤷♀️
