Thanks Gary... I 'think' I am starting to follow better.

*use case: I drained both chassis and house so low that there is not enough power to even start the generator*

Past solution in my CS: use my car to jumpstart the chassis. eventually, the chassis supplies enough power to let me start the generator. after a day of driving with both running the chassis and house are back to full capacity.

*****
When shopping for a LBB, do you focus on the words "diesel up to 8L" or on the number of Amps?

My NA is 6.7L, but has 2 1900CCA chassis batteries. Guess this means I have to hunt for a LBB that supports 6.7L and 3800CCA, if I want it strong enough to jumpstart the chassis?

Maybe the more practical approach is to buy a LBB to jumpstart the generator (475CCA), so I can use the battery boost to restore power to the chassis?

Looks like most on amazon are up to 8L and 2000A. so.. many options for the generator, but few/if any for the chassis?

But then I get confused on how the battery boost works by delivering only 50A. So, maybe I don't need a 3800A LBB to jump the chassis?

Hi walkerhound,
I try to keep things simple. The bottom line is consider having in your kit bag:
1. External battery charger (10 AMP) with boost option (50 AMP). The unit will require 120V power.
2. A lithium battery starter pack. This is in case 120V power is not available. Should be recharged once a month or so.

If there is not a short in the chassis battery(s) #1 should start a gas or diesel engine. Using the 50 AMP boost option. I recently started a Mountain Aire (newer coach forgot the engine size, it was big). Had #1 and #2 connected + jumper cables from a living engine connected.

Remember, If one connects things in parallel one adds AMPS (power) not volts.
