My partner is around 120 lbs and I'm 310. We're looking at a split adjustable base so she can raise her head while I stay flat. The salesperson said it should be fine but I'm worried about the frame twisting or the motors working harder on my side. Anyone actually used one with this kind of weight difference? Not looking for guesses from people who haven't owned one.

Would a split adjustable base work with two different body weights
We have a split king adjustable with about a 150 lb difference between us. Three years in, no real issues. The base is rated per side, so as long as your side is under the limit you should be okay. What brand are you looking at?
Check the weight capacity per side, not the total. Some split bases list a combined number that makes makes them look stronger than they are.
I'm not a big guy but my wife is tiny and we have a split base. The bigger issue for us was the gap in the middle when both sides are at different angles. She's light enough that she doesn't notice but I do. If you're a side sleeper that gap can be annoying.
That's a good point about the gap. We got the bridge thing that goes over the split and it helps some. Still not perfect but better than nothing.
Honestly I'd worry less about the weight difference and more about the mattress. A heavyy person on one side is going to compress that side of the mattress way more. If it's a split king with two twins then it's fine, but if it's one mattress split down the middle the heavier side will break down faster
Motors are usually the weak point over time, not the frame. I've seen bases handle uneven loads fine for a couple years and then one side starts lagging. Just keep that in mind.
What trailhead_kat said. Two separate mattresses is the way to go if yu can. We did that and it made a difference.
Most split adjustable bases are designed for two people of different sizes. That's kind of the whole point of a split. The per-side weight ratng is what matters. Just read the spec sheet instead of listening to the floor guy.
Looked at the spec sheet on the one we were considering and it's 400 lbs per side. So I'd have 90 lbs of headroom. My bigger concern now is the mattress situation since we were planning on a single split-top mattress rather than two separate twins.
Single split-top mattresses work but they can be a pain. If the two halves aren't the same firmness you get a weird transition in thee middle. At your weight you might want a firmer side which means ordering two different firmness levels, and not every brand lets you do thta with a single mattress.
Two separate twin XL mattresses is simpler. You can pick a fiirm one for you and a soft one for her. Downside is the gap again, but that's true either way.
