Note that the frame will definitely be wider on the 12' or 13' outfitter...so if you set it up right you could sleep cross ways on those. Unless you put a cot between bays...I've found it hard to find a nice flat spot to sleep on with your feet pointed at the bow or stern. The extra width inside the boat is big too.Great info, thanks! One thing I like about the 12 Max is that you can put a longer frame on it than on the Outfitter. I can envision some scenarios where I'm solo going very light on an overnight where I might want to rig a platform so I can throw down a bivy sack and sleep on the boat. The max frame length for the Outfitter is 5'6". That might make the difference for me. Even though I will probably never use the boat as a paddle boat. Is that the 12 Max in your photo? I love the white.
Honestly...I'd get the 13' outfitter. Way more interior room for reasonable size dryboxes and coolers for multi-day but still small enough to paddle raft with 2-7 people. It has the straight tube length you want and the extra width is nice. Its a bit heavier and about a grand more expensive though...so if you can handle the slightly shorter length you could save yourself in those ways by going with the 12'er which would also be an awesome boat. Not sure if there will be that much difference of it being rolled up compared to the Max 12 either. A little wider, but should be able to roll it to about the same diameter.
This is always a weird time to buy a used raft.... you'll see a lot more in the spring. Most people have put their rafting setup into winter storage mode.
There is definitely savings to be made by buying an entire setup from someone and you won't have to piecemeal everything. I agree that Hyside setups are hard to come by cheap...but still probably cheaper then buying it all new.
