3770FL Floorplan

Sandpiper Fifth Wheels
The 3770FL has four slide outs, two on the door side and two on the off-door side. There is a front living room with two tri-fold hide-a-bed sofas, a fireplace and entertainment center with a pop-up TV, and theater seating. The central kitchen features a large pantry, lots of counter space, a 16 CU. FT. refrigerator, microwave, cooktop and stove, plus a dinette and four chairs. Next to the kitchen is the bathroom with shower, sink, and commode. The rear bedroom includes a 60 x 80 queen bed, two dressers, and two wardrobes. Outside there is a bumper mounted swivel gas grill and outdoor refrigerator.
Our 3770FL has the same luxurious layout as our original front living floorplan at a fraction of the cost. Boasting one of the largest front cap windows in the industry, this beautiful coach offers the perfect front view. The entertainment center is second to none with a standard pop up 50” flat screen TV and over-sized fireplace for all your entertaining needs. The full walk in shower with an overabundance of headroom is something any outdoor enthusiast should not go without.

GVWR (Gross Vehicle Weight Rating)

GAWR (Gross Axle Weight Rating) – is the maximum permissible weight, including cargo, fluids, optional equipment and accessories that can be safely supported by a combination of all axles.

UVW (Unloaded Vehicle Weight)*- is the typical weight of the unit as manufactured at the factory. It includes all weight at the unit’s axle(s) and tongue or pin and LP Gas. The UVW does not include cargo, fresh potable water, additional optional equipment or dealer installed accessories.
*Estimated Average based on standard build optional equipment.

CCC (Cargo Carrying Capacity)** - is the amount of weight available for fresh potable water, cargo, additional optional equipment and accessories. CCC is equal to GVWR minus UVW. Available CCC should accommodate fresh potable water (8.3 lbs per gallon). Before filling the fresh water tank, empty the black and gray tanks to provide for more cargo capacity.

Each Forest River RV is weighed at the manufacturing facility prior to shipping. A label identifying the unloaded vehicle weight of the actual unit and the cargo carrying capacity is applied to every Forest River RV prior to leaving our facilities.

The load capacity of your unit is designated by weight, not by volume, so you cannot necessarily use all available space when loading your unit.
