Prepare to be disappointed with regards to the air conditioner and a 2000w generator.

When dry camping run your fridge off of propane. Running it on 12v will run your batteries down in a few hours, so you'll be firing up the generator every two hours. Running it on AC will require you run the generator 24/7. But it will go over 20 days on a single 20 pound propane tank.

The 2000w generator will probably not be adequate for starting up your air conditioner. People typically use two 2000w generators in parallel for that, or a single 3000w generator. There are some newer 2200w Hondas that might be able to cope with a 13000BTU air conditioner if it's in good condition. Even so, you may need to install a cold-start capacitor. The problem is that while the generator may be able to provide 2000w of power for a few seconds, the spike of load during compressor-startup is often more than 2000w, and the generator won't be able to supply that power. The compressor will fail to start up, and could even become damaged.

Well, all depended on what type of AC and trailer. I ran my Goldstar AC came with a 2012 Aliner Classic just fine with a Yamaha 1000W. I did not buy the generator for the AC, but I was surprise it ran fine in the summer.

I installed an AGM battery on my Scout for reliability. When I retired a couple of months ago, at work we had a 24 volt walk behind forklift that was used for something at least every other day. I installed four AGM batteries in it over 10 years ago. Batteries were wired 2 in a series and those 2 series were then wired in parallel. They are still going strong.

I agree that agm batteries are better and longer lasting, IF they are recharged correctly. I had this issue with dual Odyssey Batteries in my truck. They need a higher charging voltage, which the current Aliner charger may not be able to provide.

Lithium Iron Phosphate (LiFePO4) batteries are peaking my interest; in particular, the 100 Ah Battle Born battery.

Here is an article that explains the advantages of this type of battery: https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/
