Solar & batteries ...
The house battery in our Livin Lite truck camper has died after about 3.5 years of frequent use. Lots of boondocking during which it kept the fridge, LED lights, water pump, ... running for about 3-4...

Your amperage numbers a way high. It looks like you are using numbers from the product labels which will be much higher than the actual amps that they will use. The best way to check actual use would be to power up all these devices and measure the actual amps at your battery bank.
Yes.
You are misreading the amps on a few of your devices. There is no way you have 10a leds unless they're hollywood floods. Gas detectors (well, mine anyway) hardly draw. Get a meter and check every circuit at your 12v fuse panel.
jornvango numbers:
1) iPad = 3A x 4 hours of charging or use daily = 12AH
2) Cell phone = 1.5A x 4 = 6AH
3) Laptop = 16A x 4 = 64AH
4) Dometic 3-way fridge running on propane = 3.5A x 24 = 84AH
5) RV water pump = 7.5A x 0.3 = 2.25AH
6) RV furnace = 12A x 3 = 12A x 3 = 36AH
7) LED lights = 10A x 4 = 40AH
8) Camera = 4A x 4 = 16AH
9) RV radio = 4A x 2 = 8AH
10) Shaver = .67A x .3 = .2AH
11) Gas detector = 1A x 24 = 24AH
12) Inverter = .5A x 24 = 12AH
Should be (approx) :
3) Laptop 5A x 4 = 20ah
7) LED lts 1A x 4 = 4ah
11) Gas detector .1A x 24 = 2.4ah
That's 95.6 AH less than your figures.
My LEDs only draw .3 to .4A. I used 1A in the example above because you may be including double lamps.
