Solar RV Setup

I need something portable for off grid camping for my vintage 30 ft RV.

I have a propane fridge and oven, so I really just need something to charge the on board batteries for lights and the water pump, maybe brew an occasional coffee, etc. It has A/C but I doubt we'll be able to run it on any system I can afford, but feel free to prove me wrong.

I have NO idea what I actually need as far as energy storage capacity and was considering a Jackery due to the ease and the fact that I'm a complete noob to this, however I've read they are massively overpriced.

I was considering the Jackery 1500 V2 from Costco that includes 100W solar panel for $799

If you know of a similar, idiot proof setup for cheaper, I'm all ears, and not committed to this particular make or model. Our budget is under $1000 and if we could run A/C, fabulous, but not necessary.
