2026 Forest River Viking242MK

The Viking 242MK has 2,976 lbs of cargo capacity between 4,724 lbs dry and its 7,700 lbs GVWR, 39% of that rating; filling its 40-gallon fresh tank at 8.3 lb a gallon uses 332 lbs of it (how to read trailer weights).

Tongue weight is 700 lbs, 15% of the dry weight as published; it rises as the trailer is loaded and counts against the tow vehicle’s tongue-weight and payload limits (tongue weight by size).

Off hookups: 64 gallons of grey and black capacity against 40 gallons of fresh water, so fresh water runs out first (tank sizes by length).

Against the rest of the Viking roster this is the 8th of 16 floorplans by dry weight, in a line that runs from 2,499 lbs to 8,052 lbs. It sits in the middle of the line by weight.

Plan the tow on loaded weight, not the 4,724 lbs dry figure: half the published cargo capacity brings this plan to about 6,212 lbs, and the published GVWR of 7,700 lbs is the limit (how to read trailer weights).

Forest River’s line listing and this floorplan’s own factory page agree on all 4 shared figures. Dry weight plus cargo capacity equals the published GVWR exactly. A missing row means Forest River does not publish that figure (how figures are verified).

Forest River publishes no floorplan description for this plan in the channel this page is built from - only the numeric specification block. Rather than describe a layout from the floorplan code, which would be a guess dressed as a fact, this page carries what the factory publishes and says where it stops. 242MK is a Viking designation and this site does not decode it into a layout claim.

How the 242MK differs from the other fifteen Viking floorplans. Most distinctive first. Sibling pages may cover other model years than this one (2026). How these ranks are worked out.

• Cargo capacity, 2,976 lb: largest of sixteen; next is the 292TB (2,742 lb).
• Cargo capacity as a share of GVWR, 38.6%: largest of sixteen; next is the 12BH (37%).
• Tongue weight as a share of dry weight, 14.8%: second-largest of sixteen, between the 30RKDS (13.5%) and the 25TH (16.8%).
• GVWR, 7,700 lb: sixth-highest of sixteen, between the 25QBH (7,630 lb) and the 262DBS (7,725 lb).
• Tongue weight, 700 lb: sixth-heaviest of sixteen, between the 25QBH (630 lb) and the 262DBS (725 lb).
• Dry weight, 4,724 lb: eighth-lightest of sixteen, between the 18DBS (4,114 lb) and the 26BH (4,769 lb).
• Length, 26 ft 10 in: eighth-longest of sixteen, between the 22BHSR (26 ft) and the 26BH (29 ft 3 in).
• Grey tank, 32 gal: shared with the 18BH, 22BHSR and 26BH; of sixteen, three smaller and nine larger, nearest the 17BH and 17FQ (27 gal) and the 12BH, 12RD and two others (37 gal).
• Exterior height, 11 ft: shared with the 22BHSR, 25QBH and four others; of sixteen, eight lower and one taller, nearest the 25TH (10 ft 7 in) and the 30RKDS (11 ft 3 in).
• Fresh tank, 40 gal: largest of sixteen, level with the 18BH, 22BHSR and five others; next is the 18DBS (39 gal).

Next to the 18DBS, the nearest lighter floorplan by dry weight, the 242MK is 610 lb heavier by dry weight, has a GVWR 2,785 lb higher, has 2,175 lb more cargo capacity, has a tongue weight 185 lb heavier, is 3 ft 10 in longer, stands 1 ft taller, has a fresh tank 1 gal larger and has a grey tank 5 gal smaller; the two publish the same black tank.

Next to the 26BH, the nearest heavier floorplan by dry weight, the 242MK is 45 lb lighter by dry weight, has a GVWR 250 lb higher, has 295 lb more cargo capacity, has a tongue weight 250 lb heavier and is 2 ft 5 in shorter; the two publish the same exterior height, fresh tank, grey tank and black tank.

Viking is organised by weight rather than by layout, and the factory names the groupings accordingly: 3K, 4K, 5K and 6K Series. That makes it the most readable roster in this group for anyone shopping to a tow limit, because the series name is the weight class. Eighteen floorplans run 2,499 to 7,208 lb dry on lengths of 16 feet to 36 feet 8 inches, with tongue weights of 325 to 930 lb.

A full 40-gallon fresh tank is about 332 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 11% of the 242MK’s 2,976 lb cargo capacity, leaving 2,644 lb. Across 16 Viking floorplans the water share runs 11% to 55%, and this plan’s is the lowest. Nearest on that share: Viking 292TB at 12%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).
