For my Belgian beers, I use the 13 gallon "Vittles Vault" (I think it's marketed as a 55 pound container). I honestly think 2 carboys/better bottles are easier in general. Unless you can fill it in place or wheel it to your fermentation chamber, carrying 10 gallons is very difficult. I love the wide container for Belgian brews, though, but I add the second 5 gallons once it's in place.
