Do the electric fans run from the battery / electrical system which in turn is charged by the alternator / drive system,Yes instead of running off just the drive system itself where when at idle it would spin very slow and not dissipate heat very good? This depends on wether the fan has a viscious coupling or if the fan is bolted straight to the motor, a viscious fan will cut in when the temp reaches a set point and cut out out at a low point, the fixed fan runs and pulls air all the timeWhere the electric fans can run just as fast when at idle as compared to when driving?This is correct Give me a good tech explanation here. We have a 03 h2 limo for sale and are thinking about upgrading it to an 08 h2 in the spring.

Would the 08 electric fans make a big difference in AC capacity?It makes no difference at all AC is one of the biggest problems in a 25 passenger hummer limo.For this issue your best bet is to mount another seperate A/C compressor and run two aircons. Here in Aussie it's what we do with the limo's

Also the 6 speed tranny should overtime give better gas milage especially on highway , would it be worth it with GMID, compared to a leftover 07 with GMID?Can't help with this one, don't even know what GMID stands for......

Hope this helps.
