01 What makes it unique
The 3913 is the Cyclone that carries the most: Heartland publishes 5,565 pounds of cargo carrying capacity against a 21,000-pound GVWR and a 15,435-pound dry weight, and the three numbers tie out exactly. It runs forty-six feet five inches overall on a forty-five-foot-two box, sleeps eight, and sits on three 7,000-pound axles with 17.5-inch H-rated tires. The full fifth-wheel mandatory package list is standard — the 30-gallon locking fuel tank, the 3-season locking garage wall, 5,000-pound breaking-load garage D-rings on the steel frame, HappiJac electric-lift queen beds, a rear loft ladder and the lift-assisted anti-skid ramp door — alongside three Soft Start air conditioning units and the 17-cubic-foot 12-volt refrigerator.
Against the entry 3511 the trade is straightforward: five more feet, two more sleeping spots, 1,640 more pounds of cargo capacity and 3,200 more pounds of GVWR, for about thirteen thousand dollars more. The dry pin rises from 2,960 to 3,245 pounds — a modest increase for the capacity gained, because the extra load lands on a third axle rather than the hitch. This is a one-ton coach loaded, and the 5,565-pound cargo figure is a genuine number rather than a derived one, which is worth something when you are budgeting a garage full of machinery.

Towing it
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published dry figure, because loaded is never lighter than dry.
03 The Cyclone floorplan family
Heartland publishes Cyclone as two separate lines that share no floorplan codes: the Cyclone fifth wheel and the Cyclone travel trailer. Both carry the same mandatory Ramp and Cargo Equipment package — a 30-gallon fuel tank with a locking enclosed pump and timer, garage D-rings and a Tuff-Ply rubberized floor liner — and both publish their weights completely, which is rarer than it should be. The 3913 on this page is highlighted; each profiled plan links to its own page. Heartland does not publish a garage length for any Cyclone, so that column is absent from this catalog rather than estimated.
| Floorplan | Type | Length | GVWR | Sleeps | Notable |
|---|---|---|---|---|---|
| 2214 | TT | 28 ft 1 in | 11,700 | 4 | Entry Cyclone — the smallest and cheapest in the family |
| 2615 | TT | 34 ft 8 in | 13,250 | 4 | The larger trailer — most payload of the two, no published price |
| 3511 | 5W | 41 ft 2 in | 17,800 | 6 | Entry fifth wheel — the lightest pin of the three |
| 3913 | 5W | 46 ft 5 in | 21,000 | 8 | Most cargo capacity in the family — 5,565 lbs, sleeps eight |
| 3914 | 5W | 46 ft 11 in | 21,000 | 8 | The longest Cyclone — sleeps eight, heaviest pin |
| 2816 | TT | — | — | 4 | Catalogued — the factory publishes no weights for this plan |
The Cyclone fifth wheel is Heartland's premium toy hauler, and it is unusual among the lines in this catalog for how completely it publishes its weights: GVWR, dry weight, hitch weight and cargo carrying capacity are all given per plan, and dry plus cargo equals GVWR exactly on every plan that has weights. Nothing on these pages is derived. Heartland does not publish a garage length for any Cyclone, so no garage dimension appears here. Pin weights are factory dry figures and a loaded toy hauler's real pin runs well above them.
04 Notes on this floorplan
Most cargo capacity in the family
5,565 pounds — 1,640 more than the entry 3511 and 535 more than the longer 3914.
Three axles
Three 7,000-pound axles under it, against two 8,000s on the 3511 — which is why the pin only rises 285 pounds for 3,200 more pounds of GVWR.
Published, not derived
15,435 dry plus 5,565 cargo equals the 21,000-pound GVWR exactly. Every figure is Heartland's own.
No garage length
Heartland publishes no garage dimension for any Cyclone. If garage length decides it, compare against the Momentum plans, which publish theirs.
05 How it compares
A 22,500-pound-GVWR fifth wheel with 6,100 pounds of payload and a published fifteen-foot garage — at roughly the same price.
A fourteen-foot-garage luxury toy hauler with a loft, at a similar length.
Six inches longer for the same 21,000-pound GVWR — but 535 pounds less cargo capacity and a 185-pound heavier pin.
06 Loading it for a trip
A full 106-gallon fresh tank is about 884 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 16% of the 3913’s 5,565 lb cargo capacity, leaving 4,681 lb (585 lb per rated berth). Across 3 Cyclone fifth-wheel floorplans the water share runs 16% to 23%, and this plan’s is the lowest. Nearest on that share: Cyclone 3914 at 18%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits
Closest sibling: the Cyclone 3914, nearest on the published figures. It differs on 4 of the 9 fields both publish (this plan first): length 46 ft 5 in vs 46 ft 11 in; dry weight 15,435 lb vs 15,970 lb; cargo capacity 5,565 lb vs 5,030 lb; dry hitch weight 3,245 lb vs 3,430 lb. They match on sleeps, GVWR, fresh tank, grey tank and black tank.
| Cyclone fifth-wheel plans | This plan | Position, low to high | Range |
|---|---|---|---|
| GVWR (lb) | 21,000 | 2–3 of 3 | 17,800–21,000 |
| Dry weight (lb) | 15,435 | 2 of 3 | 13,875–15,970 |
| Cargo capacity (lb) | 5,565 | 3 of 3 | 3,925–5,565 |
| Dry hitch weight (lb) | 3,245 | 2 of 3 | 2,960–3,430 |
| Length | 46 ft 5 in | 2 of 3 | 41 ft 2 in–46 ft 11 in |
| Sleeps | 8 | 2–3 of 3 | 6–8 |
Either side of it by GVWR: Cyclone 3511 is 3,200 lb lighter (17,800 lb GVWR); Cyclone 3914 matches it at 21,000 lb GVWR.

11 NHTSA safety record
NHTSA holds 17 recall campaigns and 65 owner complaints against the Cyclone line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 65 complaints filed on this line the most-reported components are tires (45%), wheels (25%) and structure (11%).
Recall coverage here is not complete, and complaints are owners’ unverified reports (how this record is built). Check a specific VIN at NHTSA before you buy. Full tables are on the Cyclone line page.
