how do I find out what my LRA IS?

Check your A/C documentation or look it up online using your unit's make / model. That said, why would you care? - it's going to be somewhere in the 50 to 70 amp range, there's nothing you can do about it anyway, and other than being a curiosity it won't have any bearing on your choice of genset other than to perhaps convince you that you need to go to a larger than necessary genset . . .

I disagree with this rather pessimistic perspective.
Why would anybody care about the LRA? Well, some folks may just want to broaden their knowledge base---to better understand how RV a/c units work . . . or possibly why their RV a/c won't work (start), say, with a given generator.
Sorry, not intending to be "pessimistic" or to give the impression one shouldn't want to "broaden one's knowledge base". There's nothing wrong with research, heck I do it all the time myself about all sorts of subjects, but reality is whether LRA turns out to be 55 amps, or 60 amps, or 65 amps it's not going to change one's selection of a suitable genset. The reality also is that
any genset rated at less than 3000 - 3500 watts is going to be stressed
starting any rooftop mounted RV A/C unit regardless of what it's specific LRA may be. The solution - which I've repeated many times - is to budget for installing a Micro-Air East Start Soft Starter Kit on
any A/C and not worry about LRA which you're going to forget soon after anyway. :R
