So how does the new suction hose fit in with the existing 3880 fire engine? The answer is it does and it doesn't. It can be stored on the roof in the recessed area, although it is at the expense of other equipment such as brooms and shovels. If it is to be stored in the rear storage compartment (where the portable pump goes) it is too long, but could be trimmed down easily enough. My new slide out storage system can take it, but it does mean putting in an extra slide out above the hose one and, of course, it is at the expense of other storing other equipment. Quarts and pint pots come to mind! None of this is really a criticism of Playmobil as, after all, the 3880 has been going now for over 10 years and is smaller than the new fire engine and so complete compatibility cannot be expected.
