Spare dry suite gaskets, we’ve ended up needing them on a couple of trips now. Brush up on your replacement knowledge before you go, as well.
NRS site has a great tutorial.

I’ll second, third, fourth and fifth, the ditch boots. Most important piece of gear after dry suite, in my opinion. Uninsulated, so you can dry them out when you step in to deep at the put in!( least that’s what I usually do...)

A hot tent is REALY awesome, if you can pull it off...
