2027 Forest River Impression315MB

The Impression 315MB leaves Forest River's factory at 10,338 lbs dry with 2,875 lbs of cargo capacity. Forest River publishes no GVWR for this line, so the loaded rating is not quoted on this page and is not computed from the other two figures. What the cargo number covers is defined by the factory: fresh water, gear, food, batteries and every dealer-installed accessory come out of it. Fresh water is 8.3 lb per gallon, so filling the 57-gallon fresh tank spends 473 lbs of the 2,875 lbs before anything else goes in.

Forest River’s 2027 floorplan drawing for the 315MB shows, at the front, a 60-by-80 queen bed with Versa Tilt technology between wardrobes, a wardrobe with washer/dryer prep and a docking station. Mid-coach: a bath with a walk-in shower with skylight, and a mid bunk room with a 30-by-74 flip-down upper bunk over a 60-by-74 Versa queen in a slide, a desk, a wardrobe and a loft above with a 60-by-74 bed and a loft cubby. At the rear: a kitchen slide with a microwave, a 12-volt fridge and hidden storage, a kitchen island, an entertainment center, a tri-fold sofa and a table in a second slide, and a pantry and a desk/storage across the rear. It draws a 18-foot awning. Outside it labels two exterior mini fridges, unobstructed pass-through storage and a 2-inch receiver hitch. Layouts change with options; check the unit itself.

Pin weight is 1,935 lbs, 19% of the dry weight as published; it rises as the trailer is loaded and comes off the truck’s payload, not its towing rating, so check it against the payload on your own door sticker (pin weight and payload).

Off hookups: 92 gallons of grey and black capacity against 57 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Impression roster this is the 3rd of 10 floorplans by dry weight, in a line that runs from 7,568 lbs to 13,824 lbs. It sits in the lighter third of the line.

Plan the tow on loaded weight, not the 10,338 lbs dry figure: half the published cargo capacity brings this plan to about 11,776 lbs. Forest River publishes no loaded rating for this line, so the ceiling is the one on the trailer’s own weight label (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. No GVWR is published for this line, so dry plus cargo has no rating to check against. A missing row means Forest River does not publish that figure (how figures are verified).

Forest River publishes no written floorplan description for this plan; the layout described above is read off Forest River’s own floorplan drawing for this model year. 315MB is an Impression designation, and this site does not decode the code itself into a layout claim.

How the 315MB differs from the other nine Impression floorplans. Most distinctive first. How these ranks are worked out.

• Dry weight, 10,338 lb: third-lightest of ten, between the 235RW (8,073 lb) and the 301ML (10,443 lb).
• Cargo capacity, 2,875 lb: fourth-smallest of ten, between the 37MB2B (2,477 lb) and the 318RL (2,967 lb).
• Pin weight, 1,935 lb: fourth-lightest of ten, between the 360MYR (1,885 lb) and the 301ML (1,995 lb).
• Pin weight as a share of dry weight, 18.7%: fourth-largest of ten, between the 36BR3 (18.3%) and the 318RL (19%).
• Length, 38 ft: fourth-shortest of ten, between the 301ML (35 ft 8 in) and the 318RL (38 ft 11 in).
• Grey tank, 62 gal: fourth-largest of ten, between the 235RW, 301ML and three others (60 gal) and the 360MYR and 44STAY (90 gal).
• Exterior height, 13 ft 2 in: shared with the 235RW and 301ML; of ten, two lower and five taller, nearest the 36BR3 (13 ft 1 in) and the 318RL and 360MYR (13 ft 4 in).
• Black tank, 30 gal: smallest of ten, level with the 235RW, 301ML and two others; next is the 242RD (32 gal).

Next to the 235RW, the nearest lighter floorplan by dry weight, the 315MB is 2,265 lb heavier by dry weight, has 622 lb less cargo capacity, has a pin weight 565 lb heavier, is 9 ft 1 in longer and has a grey tank 2 gal larger; the two publish the same exterior height, fresh tank and black tank.

Next to the 301ML, the nearest heavier floorplan by dry weight, the 315MB is 105 lb lighter by dry weight, has 677 lb less cargo capacity, has a pin weight 60 lb lighter, is 2 ft 4 in longer and has a grey tank 2 gal larger; the two publish the same exterior height, fresh tank and black tank.

Impression spans a wider range than most fifth-wheel lines: the lightest plan leaves the factory under 7,600 lb dry with a 1,485 lb pin, and the heaviest is a 44-foot coach. That range crosses a real towing boundary, so the plan number matters more here than the badge does. As with Vibe, Forest River publishes no GVWR for any Impression floorplan - dry weight, cargo capacity and pin weight are published, and the rating is not.

A full 57-gallon fresh tank is about 473 lb of water, 16% of the 315MB’s 2,875 lb cargo capacity, leaving 2,402 lb. Across 10 Impression floorplans the water share runs 13% to 20%, and 3 give up more than this one. Nearest on that share: Impression 318RL at 16% and Impression 37MB2B at 19%.
