The Squrt I purchased a couple of years ago was referred to as a truck by that department - it was replaced with a 105' quint.
The following can be found in NFPA 1901 2009 edition.

meets the requirements of Chapter 16 and has a minimum
rated capacity of 1000 gpm (4000 L/min).

aerial ladder or an elevating platform with a permanently installed

My former Union worked with the Fire chief to keep 12 firefighters from being laid off. Sadly, things have changed and while no one has been laid off staffing has dropped through attrition and daily minimums keep dropping.
To me, 95% (5% shmit luck) of the time a quint can only be one or the other, so you in essences have one less functional piece of apparatus, in a volunteer setting maybe that's all you can staff right now, in a career job, it's likely there will be a day that's all they will staff.
That is one point I have been trying get thru don't sell yourselves short,buy for the future needs not today's needs. With budgets being so ever changing and call volumes changing departments need to be more open to alternative thinking about apparatus features. I see a lot of local departments buying based on trends instead of studying local fire call history and population growth and the current district roads and what possibly can be future coverage issues. What fits today's needs may lead to a shortage in the future. Giving the apparatus the extra option may not be need now but in the future could be a saving grace.
The truth is in some cases a combination rig like a tanker pumper, or a rescue engine, or perhaps a quint, may be a good idea. But trying to force a combination rig in with no other motivation than " we looked at things from a limited resource angle" may not get you what you really need to get the job done. Further, what works for you in yur little corner of the world may be 100% wrong for almost everywhere else. There is no one size fits all in the fire service.
I have a part-time job designing fire apparatus. Fyredup got it right. I see so many small communities that don't have a clue what they need except it has to be big and expensive. The fact that it's not the right fit for the FD or the community plays no part in it. There is a substantial difference in what you need and what you want.
I always thought when I was a CFR FF that our heavy rig, 2000 gpm pump, 3300 gallons of water, 500 gallons of foam, 500 pound of dry chem, with a roof and bumper turret, as well as a 200 foot 1 3/4 inch front preconnect, would have made an awesome first in rig for rural fires. Especially barn fires and such. But then again it weighed 77,000 pounds and was huge. Probably a lot of country roads it would have destroyed just driving on them.
No, I don't sell fire trucks anymore. I found it really wasn't for me.
Some FD's have no clue what they want or need, just they can't run the old truck anymore and need to replace it. They often only look as far as their nearest mutual aid (that they think is worthy) and at the magazines on the dayroom table and shoot from the hip. I know of many Fd's that go into sales meeting knowing only the type of apparatus (ladder, engine, rescue, tanker) and the amount they have budgeted.
Others go all out to ensure they're specs represent the mission of the apparatus and are typically more knowledgeable than many of the salesmen who come calling.
We have one local salesman who we had great dealings with, who knew the products and the options and was a true help in the process, but then ended up being totally off putting to a a few other local FD's. It may have been that he misread the audience in at least one case and went in too strong. I can imagine a salesman must be very patient and laid back until he knows the politics of the room. This tends to be hard for firefighters who end up in sales, as we tend to be pretty forward leaning.
I sold used apparatus for a while, and a couple of times I refused to sell a vehicle to a department because it was way off base to their needs/area. P!ssed em off big time. A couple threatened to sue me.
