Jayco Seismic Luxury Series · 2021–20254113

The Jayco Seismic Luxury Series 4113 is a fifth-wheel toy hauler in the MY2025 Seismic Luxury Series roster, with a 13' 0" garage behind the living space. Jayco publishes a dry weight of 16,000 pounds against a 20,900-pound GVWR, and the two tie out exactly with the published 4,900-pound cargo carrying capacity — 16,000 + 4,900 = 20,900. That arithmetic is checked on every plan in this catalogue, and a plan whose own figures disagree is catalogued without a page rather than quietly reconciled.

The dry pin weight is 3,670 pounds, or 23% of the dry weight. Fifth-wheel pin load lands in the truck bed and counts against the truck’s payload, not just its towing rating — it is the number that runs a truck out of payload before it runs out of tow capacity. Loaded pin runs higher than dry pin once the garage is filled. Payload is 4,900 pounds, 23% of GVWR — on a toy hauler that ceiling covers water, propane, cargo, dealer-fitted equipment AND whatever goes in the garage. Fresh water alone at 106 gallons is about 880 pounds when full.

Tanks are 106 gallons fresh, 87 grey and 87 black. Interior height is 8' 3" and the exterior measures 8' 6" wide on 215/75R17.5'H' tyres. Jayco publishes two exterior heights for this floorplan: 12' 6" at the roofline and 13' 3" with the air conditioner. Both are printed above, neither is derived from the other, and it is the taller figure that has to clear your garage door. This page covers the MY2025 4113 only. Jayco’s figures move between model years — measured on this very roster, the 395 loses more than a foot of published length between MY2026 and MY2027 — so nothing here is carried over from a neighbouring year, and no year is shown that Jayco has not published for this code.

How the Seismic Luxury Series 4113 differs from the other sixteen Seismic fifth wheels. Most distinctive first. Sibling pages may cover other model years than this one (2021–2025). How these ranks are worked out.

• Length, 46 ft 1 in: third-longest of fourteen, between the 3815 (44 ft 7 in) and the 415 (46 ft 5 in).
• Dry weight, 16,000 lb: fourth-heaviest of seventeen, between the 413 (15,985 lb) and the Seismic 4113 (16,025 lb).
• GVWR, 20,900 lb: fourth-highest of seventeen, between the 413 (20,800 lb) and the 395 and 399 (21,000 lb).
• Sleeping capacity, 8: largest of nine, level with the 399; next are the 3512, 3815 and two others (7).
• Exterior height, 12 ft 6 in: shared with the 399; of eight, one lower and five taller, nearest the 395 (12 ft 5 in) and the 359 and 413 (12 ft 7 in).
• Cargo capacity, 4,900 lb: seventh-largest of seventeen, between the 4114 (4,895 lb) and the 395 (4,925 lb).
• Dry pin weight, 3,670 lb: seventh-heaviest of seventeen, between the 3815 (3,605 lb) and the 4125 (3,685 lb).
• Dry pin weight as a share of dry weight, 22.9%: eighth-largest of seventeen, between the 3512 and 403 (22.5%) and the 4213 (23.1%).
• Cargo capacity as a share of GVWR, 23.4%: shared with the 4013; of seventeen, seven smaller and eight larger, nearest the 413 and 4213 (23.1%) and the 395 (23.5%).

Next to the 413 (2025–2027 page), the nearest lighter floorplan by dry weight, the Seismic Luxury Series 4113 is 15 lb heavier by dry weight, has a GVWR 100 lb higher, has 85 lb more cargo capacity, has a dry pin weight 200 lb heavier, is 11 in shorter, stands 1 in lower, has a black tank 37 gal larger and sleeps two more; the two publish the same interior height, fresh tank and grey tank.

Next to the Seismic 4113 (2018–2019 page), the nearest heavier floorplan by dry weight, the Seismic Luxury Series 4113 is 25 lb lighter by dry weight, has a GVWR 205 lb higher, has 230 lb more cargo capacity, has a dry pin weight 120 lb lighter, is 1 ft 10 in longer and has a fresh tank 40 gal smaller.

This floorplan has a published factory record for 5 model years here, 2021 to 2025. The specification does not hold still: GVWR runs from 20,695 lb (2021) to 20,900 lb (2025); dry weight runs from 15,815 lb (2024) to 16,195 lb (2023); dry pin weight runs from 3,550 lb (2024) to 3,900 lb (2022). The published tire size changes over the run (ST255/85R16'E', then 215/75R17.5'H'). The published sleeping capacity changes across the years: 8-9 in 2021, 7-9 in 2022, up to 10 in 2023–2024, up to 8 in 2025. Each year’s complete record is printed separately below, carrying only that year’s own published figures and source. Nothing is copied across from a neighbouring year.

Seismic Luxury Series was the top tier of Jayco's toy-hauler range, sitting above the core Seismic on fit-out and on generator and fuel provision. Jayco published it for MY2023, MY2024 and MY2025 and no model year after that, so the figures on this page are the last ones Jayco published for this floorplan. The 4113 on this page is highlighted; every other profiled plan links to its own page.

A full 106-gallon fresh tank is about 880 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 18% of the 4113’s 4,900 lb cargo capacity, leaving 4,020 lb (503 lb per rated berth). Across 17 Seismic fifth-wheel floorplans the water share runs 16% to 27%, and 12 give up more than this one. Nearest on that share: Seismic 395 at 18% and Seismic 413 at 18%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
