We use Wag Bags & Double Doodie bags (Cabelas) in a Luggable Loo every year on our 22' sailboat. Way better than a portapotty and we don't have to become contortionists to get around the compression post for the mast which is always in the way (between the main cabin and the portapotty.) We toss 'em in the trash when we get back to a marina.
We'll probably take them along when we boondock.
IMO Wag Bags control odor better than the DD's, but the DD's have a better ziplock bag setup (attached instead of separated from the "garbage" bag that goes in the luggable loo bucket. IIRC the Wag Bags include a handy-wipe and small roll of TP. We follow the "if it's yellow let it mellow" approach (within reason.)
