Thanks Bill & Pete I wasn't planing to run the air with the inverter
because it is only a 1500 watt. I was hoping to run the ice maker & laptop on
the
road without working the 160 to hard & cooking it. I do run with lights on
in the day to.

a 160 amp alternator will put out 1920 watts. An airconditioner will draw
about 1500 watts, this includes the inefficiences of the inverter, so you will
have only 400 watts or so for other things.
If you are driving during the day with your lights on that will easily
gobble up the rest of your power.
So, although a 2500 watt inverter will power your AC, and with your engine
alternator putting out 160 amps, gets real hot then, I would say it would not
be too wise to run air conditioner with your engine.
One option, expensive though, is to install the 300 amp alternator, hmmm
maybe runnning the generator would be cheaper LOL

No problem running the ice maker, some interior lights and laptop etc.
Just watch the amount of output the alternator is pushing, and adjust
accordingly.

Bill Then as long as my house battery bank stays charged & my
alternator doesn't show that it is putting out a full charge it should be okay?

The drive line retarder uses power? You would think some one could
build an electric alternator for an engine and drive line retarder
that takes the energy of a stop and produces amps to store in a
battery bank. Think of all the wasted effort it takes to hold back
40,000 lbs.

too much power in that system blows off braking energy as heat
also known as dynamic braking
you could use regenerative braking but you have to redesign the whole
coach electical and have the the lithium ion batteries to hold the
charge andthe sense and brking circuits to monitor and adapt the
charge The other down side is price of the batteries
A battery pack for a prius is around 5k to replace imgine the cost for
a 40,000 lb coach

Some electrified rail systems capture the energy from dynamic braking
(using the DC drive motors as generators) to return power to the
system. However, the equipment is expensive and heavy.
Diesel-electric locomotives also have dynamic braking - the DC drive
motors are wired to act as generators when going down grades. The
power is converted to heat via the biggest toaster grid you would
ever see. (Watch a railroad locomotive as it goes down a long grade
and you may see the 'heat waves' coming out on the top of the unit.
It will also have a characteristic dynamic brake whine if you're
within earshot.)
BBs are pretty big, but not quite in the same category as
locomotives. The expense and electrical/mechanical complexity makes
recapturing the energy not cost effective.
