I know of a couple of quints in this area that carry hard suction for portatank ops at rural fires.
1. >75 aerial with a pre-piped waterway
2. 1000GPM pump or greater
3 >300 gallons of water.
4. >85 feet of ground ladders
5. 30CF of supply line storage and 7CF of attack line storage
There are a lot of departments that are willing to sacrifice a given amount of storage space and put a pump on a ladder truck simply to eliminate the need for the pumper. They never intended for it to be a quint, don't run it as a quint, but can still use the pump to supply the aerial waterway.
The selection of a pump (and/or tank) is such a subjective issue, it has to be examined department-by-department. Obviously, many department's struggle with the "what if the ladder shows up first with no pump or water?" Well, perform a rescue where practical and absolutely necessary (VEIS), confine the fire, but the 2.5 gallon cans on it, don't break windows until a hoseline is in place. Yes, it will seem like eternity waiting for the engine to arrive, but think about it - relative to the number of calls we go on, versus the amount of those that are fire related, versus the amount that are working fires, how often is that really going to happen? As someone who runs only dry ladder trucks (all RM ladder towers) in his department, I can give you the answer: RARELY, if ever.
Our reason for running dry aerials? Our towers also run as heavy rescues (like Denver), so we need a lot of compartment space.
Let me throw in another possible complication-POLITICS.
We are a suburban 5 station department that used to run 2 truck/rescue companies (two pieces of apparatus, cross-manned) and 5 engines. Due to budget cuts, both truck companies were taken out of service. The chief sold a Tower Ladder Quint, a 75' Quint, and a Rescue to buy a used ladder with no pump or tank-so we could carry all the rescue gear on the ladder. One engine was taken out of service, and replaced by the no-pump ladder. It is the only ladder without a pump/tank in the county. It wasn't long before the ladder, running alone, got caught for extended times at fires without an engine company.
The union tried to fight the budget cuts and argued against stationing a truck without a tank/pump by itself. They pointed out we bought the pump-less ladder from a city that replaced double company houses with single quints. Citizens complained the fire department was showing up at fires and couldn't put the fire out. The other chiefs in the county complained to our city and changed the mutual aid policy to exclude our truck, as they did not want a ladder without pump filling their stations, or tying up an engine for supply at fires.
Based on all of this, the city administration forced the chief to keep 5 engines in service. The chief wants 4 engines/1 truck, so to make his point that we need the ladder in service, he will not allow us to redistribute any of the ladder company equipment. So, after being very truck company oriented for almost 20 years, we go to fires with no saws, no fans, and no ladders over 28'.
Our 1990 quint, which was supposed to be moved to reserve after the purchase of the no pump ladder, has spent 9 months in the shop getting almost $100,000 worth of repairs, including a new motor. The plan when it returns is to cross man the ladders-Quint when first due, straight ladder on other calls.
I have to ask...Are you a firefighter, a junior, a wannabe or what? Because so much of what you posts shows either little or no knowledge of fire apparatus, or standards that apply to them, or in reality, makes no sense at al when talking about tactics.
I am retired from a rural VFD member and we looked at things from a limited resource angle.
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.

184.108.40.206 The quint shall carry a minimum of 85 ft (26 m) of
fire department ground ladders to include at least one extension

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.
