Look if more trucks that is really necessary respond who cares. keep 1 K3 and use the extra crew. if you start saying "go home we don;t need you one truck is already there then one day nobody will turn up for calls." If i need assistance for whatever reason i don't really care if i get a whole group it is still help.
Mate, it just looks silly see multiple appliances turning up when they don't need to be. We tout an attempt at professionalism, yet look like dads army out for some excitement when the pager goes off.
Don't we already look like dads army in our under funded over weight 24s? 
if the reason we shouldn't allow more than 2 appliances to go is because it "looks silly" well please come up with a better reason. Because the day somebody dies and there was the chance they might not of if each brigade had brought their appliance that was on standby at the station. I will not want to be the one in court saying "i didn't respond them because it would have looked silly if it hadn't been a real fire"
You obviously have very little understanding about the way in which incidents work, especially in terms of the responding of resources.
Let say that it a nasty looking day in the middle of the fire danger season, the pagers go off, a reported grass fire in a know local bad area. Of course you are going send as many trucks per station as you can because in the case of a grass fire on a bad day, then yeah it does help to have as many appliances there as possible.
But how many times does that really happen? Not that often.
You seem to think that every incident has the ability to cause the four horsemen of the apocalypse to come storming down the main street with death carrying his sickle close behind. This is simply not the case.
A huge number of the jobs that the SACFS attend can be dealt with with a minimum of appliances. Most of the time, dual responding is only there to cover the possibility of one brigade being unable to turnout, or not having enough trained persons to respond correctly. Of course if you are a rescue brigade and need more operators, take that second truck.
Keep in mind that in terms of your argument that "Oh god if the whole group doesn't turn out, people will die" It takes your average CFS brigade 5 minutes to get out the door, 5 - 10 minutes traveling time to the job (stupidly larger in rural areas) add in a couple of minutes for Call receipt, not to mention that many fires don't get reported straight away and you are looking at the best part of 15-20 minutes. Just how well is that bloke stuck in a burning house going to be going? Yeah, not so well.
I know you're a young'un bittenyakka, and I felt the same way when I was younger, wanting to get on a truck, wanting to get to every job no matter how small. But its just not needed.
It so much easier to work with a smaller crew than every man and his dog.
