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 didn't realize I already had a 135 amp alternator. I'm thinking about getting a 2 or 3k amp power inverter to hook to my truck batteries and running a heavy ext cord to the shore power of the camper, in lieu of a generator. This would replenish my camper batteries after sitting awhile running fans, furnace, lights, etc. I could crank the truck for 20 or 30 min occasionally with a high put alternator to replenish the truck batteries. Anything wrong with this thinking?
For that size of an inverter, you need 6 gauge or less (fatter) wire and keep it as short as possible. Most alternators will not put out their full power until about 2000 RPM.
I recommend a good quality 2,000W SINE WAVE inverter. Your microwave will work better. Also, install a hard start setup on your A/C. If the A/C is on, forget about the microwave, coffe pot and hair dryer.
