I still like the bang for your buck you get from the traditional 5 gallon gerry so it holds a 5 gallon gerry behind the ladder. There
are two positions for Rotopax mounts on the ladder itself, one for the dog's two gallon water and one for the two gallons of beer , whiskey, wine or whatever
you care to fill it with. I suppose you could use the three gallon Rotopax if you had to.... for the dog that is
Please offer this beauty already!
