High Output alternators?
How common is it to swap the standard alternator out for one with high output, like 140 amp? I would like to hear from someone who has, about what performance improvement you're seeing in terms of how...

I installed a 180A alternator in my truck and I typically see continuous charge rates above 60A, and peaks over 100A (@14.7V) when the house battery is at a low SOC.
You also have a large battery bank of AGMs, which will absorb much more charge, for longer, than the typical one or two flooded cells, and added the cabling to feed them.
If you are going to do this it should be part of a complete system, as you did. Simply adding a higher output alternator to the average stock truck/camper will not result in a charge of 100A, 60A, or anything near that. It probably will not increase the rate of charge at all. For the money, most will be better served with a solar array, unless they live in the shade.
