01 What makes it unique
Heartland lists the 2023 Pioneer RK300 at 6,912 lb dry, a GVWR of 9,000 lb and a tongue weight of 728 lb. Heartland prints no cargo carrying capacity for it, so none is given here; the federal label inside the trailer carries one.
It is 35' 5 5/8" long and 11' 2" high. Heartland prints no tank capacity for it.
Among the 19 Pioneer floorplans Heartland’s 2023 Pioneer brochure lists with a published dry weight, it is number 15 from the lightest, in a range from 3,860 lb (Pioneer Trailblazer BH170) to 8,926 lb (Pioneer BH330). Every figure in that comparison is Heartland’s, for the same model year.
Every number on this page was read on 5 Nov 2026 from Heartland’s 2023 Pioneer brochure, the maker’s own dated document for model year 2023.
How the RK300 differs from the other eighteen Pioneer floorplans. Most distinctive first. How these ranks are worked out.
- Tongue weight as a share of dry weight, 10.5%: fourth-smallest of nineteen, between the RL250 (10.1%) and the BH322 (10.6%).
- Dry weight, 6,912 lb: fifth-heaviest of nineteen, between the QB300 (6,896 lb) and the BH322 (7,436 lb).
- Length, 35 ft 5 in: fifth-longest of eighteen, between the QB300 (35 ft) and the BH322 (36 ft 11 in).
- Tongue weight, 728 lb: ninth-lightest of nineteen, between the BH270 (680 lb) and the BH220 (746 lb).
- GVWR, 9,000 lb: shared with the BH322, DS320 and three others; of nineteen, eleven lower and two higher, nearest the BH281 (7,864 lb) and the BH330 (10,400 lb).
- Exterior height, 11 ft 2 in: shared with the BH220, BH270 and five others; of nineteen, six lower and five taller, nearest the BH250, RB215 and RD210 (11 ft) and the BH322, BH330 and three others (11 ft 4 in).
Next to the QB300, the nearest lighter floorplan by dry weight, the RK300 is 16 lb heavier by dry weight, has a tongue weight 78 lb lighter and is 5 in longer; the two publish the same GVWR and exterior height.
Next to the BH322, the nearest heavier floorplan by dry weight, the RK300 is 524 lb lighter by dry weight, has a tongue weight 60 lb lighter, is 1 ft 6 in shorter and stands 2 in lower; the two publish the same GVWR.

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 (9,000 lb) and the upper loaded tongue estimate (1,350 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).

04 Notes on this floorplan
What Heartland does not publish for the Pioneer RK300
Heartland prints no cargo carrying capacity, tire size, interior height, grey-tank, black-tank for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.
05 How it compares
6,896 lb dry and 9,000 lb GVWR, against this model’s 6,912 lb and 9,000 lb.
7,436 lb dry and 9,000 lb GVWR, against this model’s 6,912 lb and 9,000 lb.
07 Where this floorplan sits
Closest sibling: the Pioneer QB300, nearest on the published figures. It differs on 4 of the 5 fields both publish (this plan first): length 35 ft 5 in vs 35 ft 0 in; sleeps 6 vs 8; dry weight 6,912 lb vs 6,896 lb; hitch weight 728 lb vs 806 lb. They match on GVWR.
| Pioneer plans | This plan | Position, low to high | Range |
|---|---|---|---|
| GVWR (lb) | 9,000 | 12–17 of 19 | 4,860–11,486 |
| Dry weight (lb) | 6,912 | 15 of 19 | 3,860–8,926 |
| Hitch weight (lb) | 728 | 9 of 19 | 408–1,142 |
| Length | 35 ft 5 in | 14 of 18 | 22 ft 5 in–37 ft 7 in |
| Sleeps | 6 | 4–9 of 19 | 4–8 |
Either side of it by GVWR: Pioneer RG28 matches it at 9,000 lb GVWR; Pioneer BH330 is 1,400 lb heavier (10,400 lb GVWR).

10 Manuals & documents
Sources: heartlandrvs.com, library.rvusa.com (linked below); the full source note is at the foot of the page.
11 NHTSA safety record
NHTSA holds 14 recall campaigns and 8 owner complaints (model years 2005 on) against the Pioneer line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 8 complaints have been filed on this line — not enough to say what fails most often. They cover electrical system, structure, suspension, tires and wheels.
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 Pioneer line page.
Owner’s manuals
The maker’s own owner’s manual for each model year on this page, linked where the maker publishes it. Each link goes to the maker’s file, labelled as the maker labels it; a year with no manual of its own is not filled from another year.
| Model year | Manual |
