Sixteen gallons, 27 lb on the shipping scale. The B215 is the kind of tank you buy for a boat where every installation is done lying on your side with one arm through an access hole - light enough to...

Seventeen gallons is an honest number for a trailerable cruiser: enough fresh water for a weekend aboard without giving up a locker you actually use. The Ronco Plastics B462 puts 17 gallons into a...
