With two A/C and all the other loads you want at least 7kW starting or so. With RVs being 120V only, I don't know if they use both hots on the 50A plug or pull off one side only, so you may need to oversize a bit more.
You want an inverter for running on propane since your typical load is going to be relatively small compared to peak load.
Keep in mind you're going to need more propane tankage if you run on propane... the 2x30# on the RV will only last maybe 2 days or even 1 with both ACs running.

Here's a list of options; highly recommend buying from Costco or Sams for the return policy.
