Added CLEAN-v122
Seismic 403, from Jayco’s own model pages. Its MY2025 record publishes no change at all from MY2024 across 23 comparable fields, so that year is carried in the floorplan’s own spec table rather than given a separate address.
Octane Toy Hauler
Jayco's Octane travel-trailer toy haulers, MY2018–2019. Towed on a conventional hitch, not a fifth-wheel pin. Octane SL is the factory's badge for the lighter plans and is printed per year on each page.

Model-year records
Some floorplans in this line carry a separate record for each model year, because the published specification moves between years. On the 4113 the factory dry pin weight spans 350 lb across 2021–2025 and the tire size changes mid-run, so each year carries its own verified record, printed in full on the floorplan’s page.

01 The three rosters — measured, not assumed
Jayco files 56 Seismic URLs in its own sitemap across three separate rosters, and they are not interchangeable. Seismic is the fifth-wheel flagship and runs MY2023 to MY2027. Seismic Luxury Series sat above it and stops at MY2025 — Jayco published no later model year for it. Seismic Travel Trailer is the bumper-pull roster and appears from MY2026. Those year ranges are read out of the sitemap at build time, not typed here.
The hitch difference is the one that changes what you tow with. The two fifth-wheel rosters carry a pin weight that lands in the truck bed and counts against the truck’s payload rating; the travel-trailer roster carries a tongue weight on a ball behind the bumper. Jayco labels the row “Dry Hitch Weight” on all three, so the label is not the evidence — the fifth-wheel rosters describe their running gear around a Rota-Flex king pin, and Jayco’s own floorplan titles file the third as a travel trailer. Each table below names its own hitch column and no figure crosses between them.
Dry weight plus cargo capacity equals GVWR exactly on all 11 profiled plans — 11 exact matches, zero conflicts. GVWRs run 11,700 to 22,000 lb. This site publishes no tow ratings for specific trucks — a single truck model varies by thousands of pounds by cab, bed, axle and package — so check these figures against your own vehicle’s door-jamb ratings rather than against the segment.
02 Seismic and Seismic Luxury Series — the fifth-wheel rosters
Both are fifth-wheel toy haulers and both carry a dry pin weight, shown in its own column. Pin load sits in the truck bed and comes out of the truck’s payload alongside passengers, fuel and the hitch itself — on a garage trailer it is usually what runs a truck out of capacity first. Each code links to a full plan page.
Seismic — MY2027
| Floorplan | Exterior length | Garage | Sleeps | Dry (lb) | GVWR (lb) | Payload (lb) | Dry pin (lb) |
|---|---|---|---|---|---|---|---|
| 359 | Not published | 11' 0" | 6 | 13,490 | 17,500 | 4,010 | 2,875 |
| 399 | Not published | 13' 6" | 8 | 15,585 | 21,000 | 5,415 | 3,265 |

Seismic Luxury Series — MY2025, the last year published
| Floorplan | Exterior length | Garage | Sleeps | Dry (lb) | GVWR (lb) | Payload (lb) | Dry pin (lb) |
|---|---|---|---|---|---|---|---|
| 3512 | 41' 7" | 12' 6" | 7 | 14,285 | 18,995 | 4,710 | 3,220 |
| 3815 | 44' 7" | 15' 6" | 7 | 14,900 | 19,995 | 5,095 | 3,605 |
| 4113 | 46' 1" | 13' 0" | 8 | 16,000 | 20,900 | 4,900 | 3,670 |
Weights are Jayco’s published base-unit figures for the model year in each heading, captured from the manufacturer’s own floorplan pages. Options change every one of them, and the federal weight sticker on the trailer governs. Seismic Luxury Series figures are never carried across to a Seismic row or the reverse.
03 Seismic Travel Trailer — the bumper-pull roster
The same garage idea on a conventional ball hitch, which leaves a pickup bed free. The hitch column here is a tongue weight, not a pin weight, and it behaves differently: tongue load rides the rear axle of the tow vehicle and a weight-distributing hitch redistributes it rather than removing it. Loading the garage sits weight behind the trailer’s axles and lightens the tongue, which is its own stability problem.
| Floorplan | Exterior length | Garage | Sleeps | Dry (lb) | GVWR (lb) | Payload (lb) | Dry tongue (lb) |
|---|---|---|---|---|---|---|---|
| 214 | Not published | 14' 0" | 6 | 7,445 | 11,700 | 4,255 | 1,045 |
| 265 | Not published | 15' 0" | 6 | 8,640 | 13,250 | 4,610 | 1,270 |
| 286 | Not published | 16' 6" | 6 | 8,190 | 12,800 | 4,610 | 1,175 |
The 286 was catalogued here without figures while Jayco’s MY2027 page for it read Specs Coming Soon. Read again on 23 Oct 2026, that page publishes all four weights, which tie out exactly, so the 286 now has its own page. Like the 214 and 265, it publishes no overall exterior length; its separate Length figure is printed in the note on its page.
04 Six plans where Jayco publishes no overall exterior length
6 of the 11 profiled plans show Not published in the exterior-length row, and that row is left empty on purpose. Jayco genuinely stops publishing an Exterior Length (overall) figure for those plans — checked against the saved factory pages, not inferred from a blank field, and the 413 in the same model year still publishes one, which is what rules out a reading error.
Jayco does publish a separate Length row, and it is a different measurement rather than the same one renamed. Where this range publishes both they disagree, and not consistently in one direction: the MY2025 3815 runs 44′ 7″ overall against a 44′ 10″ length, while the 4113 runs 46′ 1″ against 44′ 5″ — twenty inches the other way. So one is not substituted for the other.
Neither is a neighbouring model year’s figure, and this roster is a good argument for why not. The 395 published 47' 3" overall for MY2026; for MY2027 it publishes no overall length at all, and its own Length row moves 46' 11" to 45' 8" across the same two years. Carrying the MY2026 number forward would have printed a figure the factory’s own other row shows to be more than a foot out. Across the 4 codes Jayco published in both MY2026 and MY2027, a median of 8 of 18 tracked fields differ, GVWR moves on 2 of 4 and dry weight on 3 of 4.
What the plan pages do instead is publish the garage length, which Jayco gives for every one of the eleven, and print the Length figure in the note where it exists so nothing is hidden. Measure the unit itself before booking a site.
05 Earlier model years, catalogued not profiled
Jayco published these rosters across the model years below. Only the year named in each table heading above is profiled with plan pages; the earlier years are recorded here so the shape of the range is visible, and their figures are never mixed into a current-year row.
| Roster | Model year | Floorplans | Codes |
|---|---|---|---|
| Seismic | MY20234 | 359, 395, 403, 405 | |
| Seismic | MY20245 | 359, 395, 399, 403, 405 | |
| Seismic | MY20255 | 359, 395, 399, 403, 413 | |
| Seismic | MY20264 | 359, 395, 399, 413 | |
| Seismic Luxury Series | MY20233 | 3512, 3815, 4113 | |
| Seismic Luxury Series | MY20243 | 3512, 3815, 4113 | |
| Seismic Travel Trailer | MY20262 | 214, 265 |
Counts are Jayco’s own floorplan URLs for each roster and model year, read off the manufacturer’s sitemap. A code appearing in two years is not evidence that the trailer is unchanged — measured on this range, most of the tracked fields move.
06 What this record does not cover
Jayco’s factory spec table for these rosters carries no slide count, no bed size, no refrigerator or air-conditioner specification, no axle count and no MSRP. Those rows are absent from the plan pages rather than filled in from a sibling floorplan or a second publisher. Tire size and garage length are published and are printed.
Recalls and owner complaints are swept for this line. Seismic was added to this site’s NHTSA roster in August 2026 and both complete recall flat files and the complete complaint flat file were read for it end to end, so the recall and owner-complaint sections below carry measured counts rather than an absence of work. One exclusion, stated rather than left silent: NHTSA also files a small number of rows under the badge Seismic Wave, which these three rosters do not cover. Measured, those rows reach no recall campaign the plain Seismic spelling already reaches, and one owner complaint, which is not counted here. A digest keyed to a model name cannot see a campaign filed against a component supplier, so check NHTSA directly by VIN before buying.
