Side sleeper here too. I bought an Enlightened Equipment Convert. I had it slightly overfilled and went with the wide. I used it for the first time 2 weeks ago in Northern Manitoba on a caribou hunt. Best money I’ve ever spent on hunting gear.
I’m on the road a lot ( heavy equipment mechanic) around Indianapolis. I see a lot of rigs every fall that have pretty much the same set up come across interstate 70. I always wonder what the story was on everyone one of them. LOL.
