01 What makes it unique
The Sundance 29RLBS leaves Heartland's factory at 9,515 lbs dry, with a published GVWR of 11,700 lbs and 2,185 lbs of cargo capacity between the two. Cargo capacity is 19% of the loaded rating, and cargo capacity is what remains for fresh water, gear, food, batteries and every dealer-installed accessory. Fresh water alone is 8.3 lb per gallon, so filling this trailer's 81-gallon fresh tank spends 672 lbs of that 2,185 lbs before anything else is loaded.
Tongue weight is 1,185 lbs, 12% of the dry weight as published; it rises as the trailer is loaded and counts against the tow vehicle’s tongue-weight and payload limits (tongue weight by size).
Off hookups: 111 gallons of grey and black capacity against 81 gallons of fresh water, so fresh water runs out first (tank sizes by length).
Against the rest of the Sundance roster this is the 2nd of 3 floorplans by dry weight, in a line that runs from 7,980 lbs to 9,620 lbs. It sits in the heavier third of the line.
Plan the tow on loaded weight, not the 9,515 lbs dry figure: half the published cargo capacity brings this plan to about 10,607 lbs, and the published GVWR of 11,700 lbs is the limit (how to read trailer weights).
Every number above was read from Heartland's own factory page for this floorplan. It was read once, from that page only, so there is no second factory listing to check it against. Dry weight plus cargo capacity also equals the published GVWR exactly, which is the arithmetic check this site runs on every profiled floorplan. Where a figure is missing from this page the row says why: either Heartland does not print it on this floorplan's page, or this capture does not carry it.
This capture carries no floorplan description for this plan - only the numeric specification block. Rather than describe a layout from the floorplan code, which would be a guess dressed as a fact, this page carries what the factory publishes and says where it stops. 29RLBS is a Sundance designation and this site does not decode it into a layout claim.
How the 29RLBS differs from the other two Sundance floorplans. Most distinctive first. How these ranks are worked out.
- Tongue weight, 1,185 lb: heaviest of three; next is the 27OKFK (1,160 lb).
- Exterior height, 11 ft 2 in: tallest of three; next is the 31BROK (11 ft 1 in).
- Fresh tank, 81 gal: largest of three; next are the 27OKFK and 31BROK (52 gal).
- Dry weight, 9,515 lb: second-lightest of three, between the 27OKFK (7,980 lb) and the 31BROK (9,620 lb).
- GVWR, 11,700 lb: second-lowest of three, between the 27OKFK (9,800 lb) and the 31BROK (11,995 lb).
- Cargo capacity, 2,185 lb: second-smallest of three, between the 27OKFK (1,820 lb) and the 31BROK (2,375 lb).
- Cargo capacity as a share of GVWR, 18.7%: second-smallest of three, between the 27OKFK (18.6%) and the 31BROK (19.8%).
- Tongue weight as a share of dry weight, 12.5%: second-smallest of three, between the 31BROK (11.5%) and the 27OKFK (14.5%).
- Length, 37 ft 11 in: second-shortest of three, between the 27OKFK (31 ft 7 in) and the 31BROK (38 ft 8 in).
Next to the 27OKFK, the nearest lighter floorplan by dry weight, the 29RLBS is 1,535 lb heavier by dry weight, has a GVWR 1,900 lb higher, has 365 lb more cargo capacity, has a tongue weight 25 lb heavier, is 6 ft 4 in longer, stands 2 in taller and has a fresh tank 29 gal larger; the two publish the same grey tank, black tank and sleeping capacity.
Next to the 31BROK, the nearest heavier floorplan by dry weight, the 29RLBS is 105 lb lighter by dry weight, has a GVWR 295 lb lower, has 190 lb less cargo capacity, has a tongue weight 75 lb heavier, is 9 in shorter, stands 1 in taller, has a fresh tank 29 gal larger and sleeps four fewer; the two publish the same grey tank and black tank.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (11,700 lb) and the upper loaded tongue estimate (1,755 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
Loaded range: 10–15% of GVWR on the tongue, 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 figure, because loaded is never lighter than that.
03 The Sundance floorplan family
Sundance is Heartland's travel-trailer roster under the Sundance name. Heartland publishes 3 floorplans with a 2027 Quick Specs page and all 3 are profiled here, from 7,980 lb dry (27OKFK, 31' 7" long) to 9,620 lb dry (31BROK, 38' 8" long), with published hitch weights of 1,110 to 1,185 lb. Dry weight plus cargo carrying capacity equals the published GVWR exactly on 3 of 3.
| Floorplan | Nominal | Dry weight (lb) | GVWR (lb) | Notable |
|---|---|---|---|---|
| 27OKFK | 31' 7" | 7,980 | 9,800 | Travel Trailers |
| 29RLBS | 37' 11" | 9,515 | 11,700 | Travel Trailers |
| 31BROK | 38' 8" | 9,620 | 11,995 | Travel Trailers |
These are Heartland's 2027 Sundance travel-trailer records. Heartland's 2026 records for 29RLBS and 31BROK publish different figures and are not merged into these pages; they are printed on the Sundance hub, as is 27RBSS (2026), whose published figures do not reconcile.
04 Notes on this floorplan
What this page does not carry
Heartland's Quick Specs pages also print axle count and MSRP; this capture does not carry them, so they are absent here rather than estimated. Sleeping capacity is shown as Heartland prints it, and tire size only where Heartland prints one. A tire size is a safety-relevant number that differs between two codes a digit apart, and this site does not guess one.
Weigh it before you tow it
Every figure on this page is a factory publication for a standard build. Heartland's pages note that actual floor plans, features and finishes may vary, and options, dealer-installed accessories and the previous owner's additions all move a trailer's weight. The only weight that governs your towing decision is the one under your own trailer on a scale, loaded the way you actually travel.
05 How it compares
7,980 lbs dry against this plan's 9,515 lbs, a difference of 1,535 lbs.
9,620 lbs dry, 105 lbs more than this plan, and 2,375 lbs of cargo capacity against this one's 2,185 lbs.
2,375 lbs of cargo capacity, the highest of the 3 Sundance floorplans profiled here. If payload rather than length is the binding constraint, that is the plan to compare against.
06 Loading it for a trip
A full 81-gallon fresh tank is about 672 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 31% of the 29RLBS’s 2,185 lb cargo capacity, leaving 1,513 lb (378 lb per rated berth). Across 3 Sundance floorplans the water share runs 18% to 31%, and this plan’s is the highest. Nearest on that share: Sundance 27OKFK at 24%. 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 Sundance 27OKFK, nearest on the published figures. It differs on 6 of the 9 fields both publish (this plan first): length 37 ft 11 in vs 31 ft 7 in; dry weight 9,515 lb vs 7,980 lb; GVWR 11,700 lb vs 9,800 lb; cargo capacity 2,185 lb vs 1,820 lb; hitch weight 1,185 lb vs 1,160 lb; fresh tank 81 gal vs 52 gal. They match on sleeps, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 18 recall campaigns and 19 owner complaints (model years 2005 on) against the Sundance Fifth Wheel line (a recall and a complaint are not the same thing).
What to look at on a used one. Across the 19 complaints filed on this line the most-reported components are tires (53%), wheels (16%) and unknown or other (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 Sundance Fifth Wheel line page.
