well 24P and 34P appliances still serve a purpose for brigades that need an appliance(s) to serve a dual role of both urban type incidents as well as rural type jobs, So type 2 pumpers arent suitable for everyone.
24P,34P = 500gpm pumps. about 1900 litres per minute
Type 2 = 750gpm pumps. about 3000 litres per minute.
so yes there is a bit of difference.
