I haven't used my Mini Max for R2, nor have I done any overnights in it, but it would probably carry two paddlers and gear for a couple days depending on how light you pack.
I have had it setup as an oarboat on some technical class IV and in some bigger water class II/III with, er, mixed results. I say mixed because I was charging everything at first and soon found out that it was less forgiving than my 14' boat. It would get surfed and ejected me a few times and flipped once before I decided to take it easy and sneak stuff. It's lighter than an Aire, but less stable. With two paddlers and some gear in it it would probably be more stable. Fun boat for sure, it's nice not having to break the back carrying it. Also I think it;s a bit less expensive than an Aire, or the Sotar (which would be my first choice if I had unlimited $$). Look for the year end deals Hyside has.
more snow = more water
