Let's say your fleet is only 25 machine but, it happens to be a foundry type application, is one tech enough? Maybe. All the talk back and forth within this forum is a very positive thing to happen, i'm all for it but, anyone that's been in our business any length of time should know what's reality and productive. If everyone would read between the lines you can narrow it down to just a few factors.

1. type of equipment (IC, type of fuel, elec)
2. how much equipment location has to maintain
3. application (match equipment to applications)
4. in-house support (tech experiance)(safety)
5. external support (dealer)
6. pm frequency

All factors listed above will determine how many tech's, in-house & local suppot is needed to safely maintain your fleet. If you have the experiance, if you keep current with mobile equipment products, have good local dealer support as well as, in-house support such as, pro-active management and safety departmen will increase your ability to maintain your fleet. Maybe even a fleet as large as 200-250 machines. Personally I think it's impossible unless your fleet happens to be only pallet jacks.
