Liquid Tender Trailers

Our Demco liquid tender trailers combine dual 3,250-gallon tanks with open deck space. Both tandem models carry 6,500 gallons and use Demco's basic plumbing package.

42- or 48-Foot Liquid Tender Trailer

Model Total Tank Capacity Deck Length Plumbing
Demco 42-foot Liquid Tender Trailer 6,500 gallons in two 3,250-gallon tanks 15 feet 6 inches Basic package
Demco 48-foot Liquid Tender Trailer 6,500 gallons in two 3,250-gallon tanks 21 feet Basic package

The 48-foot trailer provides 5 feet 6 inches more deck length while retaining the same listed liquid capacity. The basic plumbing package connects fittings, hose, and valves from both tanks to a central fill-bank valve cluster on the deck. Deluxe and premier plumbing or induction systems are optional, so confirm the selected package before ordering.

Axles and Loaded Weight

Both tandem models use closed-tandem SAF Holland spring suspension with two 22,500-pound axles and ABS on one axle. Component ratings do not establish legal payload. Confirm the truck, liquid density, axle loading, weight distribution, and hauling requirements for each load.
