Jayco Eagle HT · 2025–202631QCD

The Jayco Eagle HT 31QCD is a 36' 6" fifth wheel in the MY2026 Eagle HT roster. Jayco publishes a dry weight of 9,835 pounds against a 11,700-pound GVWR, and the two tie out exactly with the published 1,865-pound cargo carrying capacity — 9,835 + 1,865 = 11,700. That arithmetic is checked on every plan in this catalogue, and a plan whose own figures disagree is catalogued without a page rather than quietly reconciled.

The dry pin weight is 2,080 pounds, or 21% of the dry weight. Fifth-wheel pin loads land in the truck bed and count against payload, not against the receiver rating, so the number that matters is your truck’s remaining payload with passengers and gear aboard. Payload is 1,865 pounds, 16% of GVWR — that is the ceiling for water, propane, cargo and any dealer-fitted equipment combined. Fresh water alone at 52 gallons is about 432 pounds when full.

Tanks are 52 gallons fresh, 82 grey and 45 black, and the factory lists ST225/75R15'E' tires. Interior height is 6' 2" and the exterior measures 8' 1" wide by 12' 2" tall — check that height against your own garage, and remember an air-conditioner shroud adds to it. This page covers the MY2026 31QCD only. Jayco’s figures move between model years — measured on one Eagle floorplan across five consecutive years, 20 of 28 published fields changed, including tire size and a 290-pound swing in dry pin weight — so nothing here is carried over from a neighbouring year, and no year is shown that Jayco has not published for this code.

How the 31QCD differs from the other 51 Eagle fifth wheels. Most distinctive first. Sibling pages may cover other model years than this one (2025–2026). How these ranks are worked out.

• Dry pin weight as a share of dry weight, 21.1%: shared with the 360DBOK; of 52, 49 smaller and one larger, nearest the 28CRT (20.7%) and the 29CBD (21.8%).
• Exterior height, 12 ft 2 in: shared with the 30RLT, 31RLT and 34MBL; of 35, two lower and 29 taller, nearest the 29CBD (11 ft 10 in) and the 24MLE, 25RUC and eight others (12 ft 3 in).
• Sleeping capacity, 7: shared with the 31MB, 31MBT and 31QBH; of 37, 29 smaller and four larger, nearest the 27RS, 29DDB and four others (6) and the 28BHU, 34MBL and 355MBQS (8).
• Cargo capacity, 1,865 lb: thirteenth-smallest of 52, between the 29.5FBDS (1,860 lb) and the 30CRT (1,875 lb).
• Cargo capacity as a share of GVWR, 15.9%: thirteenth-smallest of 51, between the 28CRT (15.8%) and the 29DDB (16%).
• Interior height, 6 ft 2 in: lowest of 46, level with the 25.5REOK, 27.5RLTS and nine others; next is the 28RKS (6 ft 3 in).
• Dry pin weight, 2,080 lb: shared with the 321RSTS; of 52, 34 lighter and sixteen heavier, nearest the 29CBD (2,075 lb) and the 325MKTS (2,081 lb).
• Length, 36 ft 6 in: shared with the 317RLOK; of 44, 26 shorter and sixteen longer, nearest the 30.5MBOK (36 ft 2 in) and the 319MLOK (36 ft 9 in).
• Dry weight, 9,835 lb: 22nd-heaviest of 52, between the 34MBL (9,810 lb) and the 30.5MBOK (9,970 lb).
• GVWR, 11,700 lb: shared with the 31QBH and 34MBL; of 52, 28 lower and 21 higher, nearest the 30CRT and 31RLT (11,600 lb) and the 30.5MBOK (11,950 lb).
• Fresh tank, 52 gal: shared with the 24MLE, 25RUC and thirteen others; of 52, thirteen smaller and 23 larger, nearest the 28BHU, 28RKS and 31QBH (51 gal) and the 325BHQS, 327CKTS and 339FLQS (75 gal).
• Grey tank, 82 gal: shared with the 24MLE, 25RUC and eighteen others; of 52, fourteen smaller and seventeen larger, nearest the 27RL and 27RS (80 gal) and the 317RLOK, 319MLOK and thirteen others (87 gal).
• Black tank, 45 gal: shared with the 24MLE, 25RUC and eighteen others; of 52, fourteen smaller and seventeen larger, nearest the 27RL and 27RS (43 gal) and the 317RLOK, 319MLOK and nine others (50 gal).

Next to the 34MBL (2027 page), the nearest lighter floorplan by dry weight, the 31QCD is 25 lb heavier by dry weight, has 25 lb less cargo capacity, has a dry pin weight 260 lb heavier, is 9 in shorter, has 2 ft 3 in less interior height and sleeps one fewer; the two publish the same GVWR, exterior height, fresh tank, grey tank and black tank.

Next to the 30.5MBOK (2019–2020 page), the nearest heavier floorplan by dry weight, the 31QCD is 135 lb lighter by dry weight, has a GVWR 250 lb lower, has 115 lb less cargo capacity, has a dry pin weight 285 lb heavier, is 4 in longer, has a fresh tank 29 gal smaller, has a grey tank 17 gal larger and has a black tank 12.5 gal larger; the two publish the same interior height.

This floorplan has a published factory record for 2 model years here, 2025 to 2026. The specification does not hold still: dry weight runs from 9,817 lb (2025) to 9,835 lb (2026); dry pin weight runs from 2,080 lb (2026) to 2,215 lb (2025). Each year’s complete record is printed separately below, carrying only that year’s own published figures and source. Nothing is copied across from a neighbouring year.

Jayco's Eagle is the brand's premium towable family, and it splits three ways. The full-size Eagle is the flagship fifth wheel — Stronghold VBL™ laminated walls, 5-Star Handling, the HELIX dual-15,000-BTU cooling system and a 16 cubic-foot residential refrigerator. Jayco offers the Eagle HT line as both a fifth wheel and a travel trailer — lighter, 4-Star Handling with Goodyear Endurance tires, and lower pin or tongue weights. The 31QCD on this page is highlighted; each other profiled plan links to its own page. The full Eagle catalogue runs to dozens of floorplans across all three; the highest-demand layouts are detailed here and the rest are catalogued on the line hub.

A full 52-gallon fresh tank is about 432 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 23% of the 31QCD’s 1,865 lb cargo capacity, leaving 1,433 lb (205 lb per rated berth). Across 52 Eagle fifth-wheel floorplans the water share runs 16% to 34%, and 34 give up more than this one. Nearest on that share: Eagle 30CRT at 23% and Eagle 28CRT at 24%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
