01 What makes it unique
The 3511 opens the Cyclone fifth-wheel line at forty-one feet two inches overall on a forty-foot box, sleeping six on two 8,000-pound axles and 17.5-inch H-rated tires. Its mandatory Ramp and Cargo Equipment package is the fuller of the two Cyclone bodies: a 30-gallon fuel tank with locking enclosed pump and timer, a 3-season locking garage wall, 5,000-pound minimum breaking-load garage D-rings mounted to the steel frame, HappiJac electric-lift queen beds with convertible sofas, a rear loft ladder, a lift-assisted weatherproof anti-skid ramp door and a powder-coated aluminum patio kit with gate and entry steps. The mandatory Camping in Comfort package brings three high-efficiency Soft Start air conditioning units, a 12-volt black glass 17-cubic-foot refrigerator, 106 gallons of fresh water, 60-pound LP bottles, a 60,000-BTU on-demand tankless water heater and solid surface countertops.
The weights are published complete and tie out exactly: 13,875 pounds dry plus 3,925 pounds of cargo equals the 17,800-pound GVWR. The 2,960-pound dry pin is the lightest of the three fifth wheels. Read the cargo figure with care — 3,925 pounds is a real toy budget, but the 30-gallon fuel tank and 106 gallons of fresh water can claim several hundred pounds of it before anything with wheels goes in the back. Heartland publishes no garage length for this or any Cyclone, so if garage dimensions decide your purchase, the comparison you want is against the Momentum plans profiled here, which publish theirs.

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 3511 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
Lightest pin of the Cyclone fifth wheels
2,960 pounds dry — against 3,245 on the 3913 and 3,430 on the 3914.
Three A/C units, published as a count not a rating
The mandatory Camping in Comfort package specifies three high-efficiency Soft Start units. Heartland gives no BTU rating for the fifth wheels, so none is stated here.
5,000-pound breaking-load D-rings
The fifth-wheel garage D-rings carry a published 5,000-pound minimum breaking-load rating mounted to the steel frame. The Cyclone travel trailers publish D-rings with no rating.
No garage length
Heartland publishes no garage dimension for any Cyclone. Omitted rather than estimated.
05 How it compares
A 16,400-pound-GVWR fifth-wheel toy hauler with a published eleven-foot garage and a lighter 2,300-pound pin.
The luxury fifth-wheel toy-hauler entry — a step up in finish and price.
Five feet longer, sleeps eight, and 1,640 more pounds of cargo capacity on a 21,000-pound GVWR.
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), 23% of the 3511’s 3,925 lb cargo capacity, leaving 3,041 lb (507 lb per rated berth). Across 3 Cyclone fifth-wheel floorplans the water share runs 16% to 23%, and this plan’s is the highest. 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 3913, nearest on the published figures. It differs on 6 of the 9 fields both publish (this plan first): length 41 ft 2 in vs 46 ft 5 in; sleeps 6 vs 8; dry weight 13,875 lb vs 15,435 lb; GVWR 17,800 lb vs 21,000 lb; cargo capacity 3,925 lb vs 5,565 lb; dry hitch weight 2,960 lb vs 3,245 lb. They match on fresh tank, grey tank and black tank.

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.
