Specification data for towable RVs is unusually dirty. Factory pages roll to the next model year and take the old numbers with them; brochures are superseded without being withdrawn; and dealer listings replicate each other's transcription errors until the wrong figure looks like consensus. This page sets out the standard every figure on this site has to clear before it is published — and, just as importantly, what happens to the figures that do not clear it.
The same standard, machine-readable
The five points below are published verbatim in /llms.txt so that automated systems citing this catalog read the identical rules a human reader does. If the two ever disagree, the discrepancy is a defect — they are generated from one source.
01 The five-point standard
1. Named sources onlyprovenance
Specifications come from manufacturer factory pages, manufacturer brochures, and structured dealer-network spec records. Each line documents which source supplied which field. No figure enters the catalog from an unattributed aggregator, a forum post, or a competitor's page.
2. Cross-checkingconflict logging
Where two sources disagree, the conflict is logged on the page itself rather than silently resolved. Factory data is treated as authoritative when a conflict has to be broken, and the losing figure is still printed with its source so a reader who encounters it elsewhere knows why it differs.
3. Weight tie-outarithmetic proof
Where a line publishes dry weight, cargo capacity and GVWR, the identity dry + CCC = GVWR must hold exactly. It is a genuine test: a transcription error in any of the three breaks it. Plans that fail the tie-out are published with the mismatch flagged on the page, not quietly reconciled by adjusting one of the numbers.
4. No estimationthe cardinal rule
A field that no source publishes is shown as not published, or the row is omitted. It is never inferred from a sibling floorplan, from the line's other model years, or from segment convention. Where a figure is derived — obtained by adding two published values rather than read directly — it carries a visible asterisk through every downstream surface, including the spec-sheet PDF. 70 of the 531 floorplans in the tow index use a derived GVWR on that basis.
5. Exclusion over guessingthe expensive part
22 floorplans are deliberately excluded from the tow index because a figure the calculation requires does not exist in any published source for them. They get no tow block at all rather than a partial or estimated one. A floorplan with a missing GVWR is a floorplan this site will not tell you how to tow.
02 Source hierarchy
When sources conflict, they are ranked in this order, and the ranking is applied consistently rather than per-figure:
- Manufacturer factory pages for the matching model year — the primary record, and the only source that reflects a mid-year re-spec.
- Manufacturer brochures for the matching model year — durable in a way factory pages are not. When a factory page rolls to the next year and takes a figure with it, the model-year-matched brochure becomes the citable source of record.
- Structured dealer-network spec records — broad coverage and consistent field structure, but the most likely of the three to carry a stale figure from a prior model year.
- Dealer listings and editorial write-ups — used only to corroborate a layout description. No weight, capacity or price in this catalog rests on one.
03 What the flags mean
Three markers appear on floorplan pages, and each one means something specific:
| Asterisk on a value | Derived by arithmetic from published figures, or published by a single source only. Not directly published as printed. |
| “Not published” | No source in the hierarchy publishes this field for this floorplan. The gap is deliberate. |
| Conflict note | Two sources disagree. Both figures and both sources are stated; the page does not pretend the disagreement was resolved. |
Every floorplan page carries a data-completeness figure at the foot, which is the share of the fields this catalog tracks that a named source actually publishes for that plan. A completeness figure below 90% is not a defect in the page — it is a measurement of how much its manufacturer publishes.
04 Towing figures — the rules that matter most
Every hitch, tongue and pin weight on this site is a dry figure
It is the manufacturer's number for an empty trailer. Loaded tongue weight — with fresh water, propane, batteries and gear aboard — runs materially higher. Sizing a tow vehicle against the dry number is the most common and most consequential towing mistake, and it is the reason the tow block on each floorplan page leads with loaded weight rather than dry.
The tow block published on 531 floorplan pages (369 travel trailers, 162 fifth wheels) states three things and refuses to state a fourth:
- The minimum tow rating the trailer requires, which is its GVWR — the loaded ceiling, not the dry weight. This is the number that binds.
- The payload arithmetic you must perform against your own vehicle, using the published dry hitch figure as a floor and not as an answer.
- Hitch class and weight-distribution band, per the published SAE J684 classification.
- Never a tow rating for a named vehicle. One truck nameplate spans thousands of pounds of capability across engine, axle ratio, cab, drivetrain and trim. Any figure claiming otherwise is a number this site did not verify, and pairing one with a trailer weight from here produces an answer neither source stands behind.
05 Model years and change over time
Each floorplan page covers a floorplan code as a span rather than a single model year, with year-specific notes where a plan was re-specified. This is deliberate: a floorplan that ran for nine years is one thing a buyer is shopping for, not nine separate things, and roughly two-thirds of towable RV purchases are of used units. Where a figure applies to one model year and not the whole span, the page says which year it is from.
06 What is deliberately not published
- Ratings and reviews. No star scores, no aggregate ratings. There is no honest way to produce them across a catalog this size, and fabricating them to earn a rich-result badge would violate the standard on this page.
- Availability and offers. This site sells nothing, so no page claims a unit is in stock or available at a price.
- Fields the manufacturer withholds. Tire size, axle ratings and interior height are published inconsistently across the industry. Where a line does not publish one, this catalog leaves it blank rather than reading it across from a sibling plan.
07 How this is enforced
The standard is not a promise, it is a build gate. Pages are generated from verified per-line records, and the whole tree must pass a twelve-check validation run before anything ships. Ten of the 12 checks run against every page: unreplaced template tokens, document structure, structured-data parsing, internal-link resolution, flagged-field notes, canonical and Open Graph agreement, character-escape leakage, dead in-page links, structured-data URL integrity, and agreement between every internal link and the canonical URL of its target.
The remaining two check the machinery rather than the output, because that is where the errors were actually coming from. One classifies every page at the site root and refuses to let a new non-floorplan page enter the tree without being registered in all four generators that publish a floorplan count — the failure it prevents is a published count that inflates silently while every page-level check stays green. The other compares every build script against its duplicate copies and fails on any byte of difference, after four copies were found to have drifted apart unnoticed. A run that fails any check does not ship — which is the only version of a standard that survives contact with a deadline.
