I got a harness from Cirilla's It goes by the name Sportsheets harness, we have the plus size version with a "corset-lace up" back style (I tried linking it, but the post didn't like that lol)
I purchased it awhile back (though mine is black) and love it. My husband and I have used it on several toys I believe ours was the medium razor and fenrir and possibly medium seadragon. The nice part is that you can swap out the O-rings so I assume you could just buy a larger O-ring to hold the base of the larger toys for you. You might need to squeeze the silicone to get it settled in, but with a bit of wiggle I've gotten my toys in just fine.
Best of luck on finding a good fit for your harness!
