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.

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 What owners & reviewers report
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.
