Wet floorboard in 2002 Dakota!

Q: i believe the power inverters run at 115 volts. v*a=w volts x amps = watts so 800 watts at 115 volts is 6.9 amps 800 watts at 12 volts is 66.6amps. does this sound accurate yes but you have to add a little for inefficiencies in power conversion and delivery. i your present alternator already generates over 1 kw 130 amps at 12 v = 1560 watts wow. so it means that i could easily connect a big inverter to the battery posts and draw say 800 watts at idle would that be safe my truck does have a heavy duty package i did not think about it. my primary use for such an inverter would be to power the furnace blower and maybe a tv or a computer or a radio. obviously only the furnace blower consumes significant power. in summer i could use it to power our two refrigerators. so i am talking about a 300-700 watt real load. thanks i there is an ongoing military program to provide the army with pickup trucks that also have a 20kw generator connected to the engine. such trucks could provide power at remote sites during deployment of troops. it sounds like a great idea. what i am thinking about right now is whether it is possible to replace an existing car alternator with one that could generate say 1 kilowatt of electricity. i have a pickup truck and with such an aleranator and an inverter i could have a great standby power capacity. i have a 1999 dodge ram truck and i know that there is enough space under the hood to mount a bigger alternator. are such extra powerful alternators available .

does anyone know about the phenomenom with these 3.3 liter motors whereby with only as little as 75000 miles on it a rocker tower breaks is it a problem that has to be fixed right away or can it just be driven until something physically breaks. all i hear right now is the tapping sound mostly under acceleration. no other symptons. both a dealer service and my private mechanic diagnosed the same thing independent of each other with the dealer quoting $1200 to repair ouch!. good ole american engineering! .
