01 What makes it unique
The 3914 is the biggest Cyclone Heartland builds: forty-six feet eleven inches overall on a forty-five-foot-eight box, sleeping eight on three 7,000-pound axles. It shares the 3913's 21,000-pound GVWR and its full mandatory package content — the 30-gallon locking fuel tank with enclosed pump and timer, the 3-season locking garage wall, 5,000-pound breaking-load garage D-rings mounted to the steel frame, HappiJac electric-lift queen beds with convertible sofas, a rear loft ladder, three Soft Start air conditioning units, the 17-cubic-foot 12-volt black glass refrigerator and 106 gallons of fresh water.
The comparison against the 3913 is where this plan gets interesting, because it is not simply bigger. Six inches more length costs 535 pounds of cargo capacity — 5,030 against 5,565 — and adds 185 pounds to the pin, at 3,430 pounds against 3,245, for the same 21,000-pound GVWR and about 750 dollars more. The dry weight is 535 pounds higher, which is exactly where the cargo capacity went. If the extra six inches buys you the layout you want, the trade is fine; if it does not, the 3913 carries more for less.

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 3914 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
Heaviest pin in the family
3,430 pounds dry — 470 more than the entry 3511. Confirm your truck's rear-axle rating with the garage loaded, not empty.
535 pounds less cargo than the 3913
Same 21,000-pound GVWR, six inches longer, 535 pounds heavier dry — and the cargo capacity drops by exactly that. The dry weight is where it went.
Published, not derived
15,970 dry plus 5,030 cargo equals the 21,000-pound GVWR exactly.
No garage length
Heartland publishes no garage dimension for any Cyclone floorplan. Omitted rather than estimated.
05 How it compares
Six inches shorter, 535 more pounds of cargo capacity and a lighter pin, for about 750 dollars less.
Grand Design's flagship family plan — sleeps nine on a 23,500-pound GVWR with a published seventeen-foot garage, at about fifty thousand dollars more.
Six feet shorter on a 17,800-pound GVWR, sleeping six, with the lightest pin of the three.
