Awesome trip report! I was there a few weeks ago for the first time and it was amazing. How was sleeping by the lake? We were going to camp there for the night but figured the mosquitoes would eat us alive so we backtracked and camped about a few miles up.
Snow Peak Pack & Carry. Folds flat and built well. It isn't cheap but does come with a variety of accessories. I have both the small (for solo trips) and the medium. I would recommend it if you don't mind using charcoal or firewood.
I'm running the FRO's Slimline II on my JKUR and using the supplied foam washers. I've seen someone use silicone on it but haven't asked how it went for them. I've had the rack for about 4 months and so far no leaks.
