Jayco Seismic · 2025–2027413

The Jayco Seismic 413 is a fifth-wheel toy hauler in the MY2027 Seismic roster, with a 14' 0" garage behind the living space. Jayco publishes a dry weight of 15,985 pounds against a 20,800-pound GVWR, and the two tie out exactly with the published 4,815-pound cargo carrying capacity — 15,985 + 4,815 = 20,800. 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 3,470 pounds, or 22% 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 4,815 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 50 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' 7" 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 MY2027 413 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 413 differs from the other sixteen Seismic fifth wheels. Most distinctive first. Sibling pages may cover other model years than this one (2025–2027). How these ranks are worked out.

• Length, 47 ft: longest of fourteen; next is the 415 (46 ft 5 in).
• Dry weight, 15,985 lb: fifth-heaviest of seventeen, between the 4212 (15,925 lb) and the Seismic Luxury Series 4113 (16,000 lb).
• GVWR, 20,800 lb: fifth-highest of seventeen, between the 4013, 4114 and four others (20,695 lb) and the Seismic Luxury Series 4113 (20,900 lb).
• Dry pin weight as a share of dry weight, 21.7%: fifth-smallest of seventeen, between the 395 and 4250 (21.5%) and the 4212 (21.9%).
• Black tank, 50 gal: smallest of eleven, level with the 3815; next are the 3512, 359 and seven others (87 gal).
• Sleeping capacity, 6: smallest of nine, level with the 359 and 415; next are the 3512, 3815 and two others (7).
• Dry pin weight, 3,470 lb: seventh-lightest of seventeen, between the 395 (3,450 lb) and the 4212 (3,495 lb).
• Cargo capacity, 4,815 lb: eighth-smallest of seventeen, between the 4212 (4,770 lb) and the 4013 (4,850 lb).
• Exterior height, 12 ft 7 in: shared with the 359; of eight, three lower and three taller, nearest the 399 and Seismic Luxury Series 4113 (12 ft 6 in) and the 403 (12 ft 8 in).
• Cargo capacity as a share of GVWR, 23.1%: shared with the 4213; of seventeen, five smaller and ten larger, nearest the 4212 (23%) and the 4013 and Seismic Luxury Series 4113 (23.4%).

Next to the 4212 (2018–2019 page), the nearest lighter floorplan by dry weight, the 413 is 60 lb heavier by dry weight, has a GVWR 105 lb higher, has 45 lb more cargo capacity, has a dry pin weight 25 lb lighter, is 3 ft 5 in longer and has a fresh tank 40 gal smaller.

Next to the Seismic Luxury Series 4113 (2021–2025 page), the nearest heavier floorplan by dry weight, the 413 is 15 lb lighter by dry weight, has a GVWR 100 lb lower, has 85 lb less cargo capacity, has a dry pin weight 200 lb lighter, is 11 in longer, stands 1 in taller, has a black tank 37 gal smaller and sleeps two fewer; the two publish the same interior height, fresh tank and grey tank.

This floorplan has a published factory record for 3 model years here, 2025 to 2027. The specification does not hold still: GVWR runs from 20,400 lb (2025) to 20,800 lb (2027); dry weight runs from 15,185 lb (2025) to 15,985 lb (2027); dry pin weight runs from 3,345 lb (2025) to 3,470 lb (2027). 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 is Jayco's fifth-wheel toy-hauler flagship — a garage trailer built to carry motorcycles, side-by-sides or a track bike. Jayco's own floorplan titles call it a toy hauler, and the running gear is described around a Rota-Flex king pin, so the hitch figures on this page are PIN weights, carried in the truck bed and counted against the truck’s payload rating. The 413 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 413’s 4,815 lb cargo capacity, leaving 3,935 lb (656 lb per rated berth). Across 17 Seismic fifth-wheel floorplans the water share runs 16% to 27%, and 11 give up more than this one. Nearest on that share: Seismic 4113 at 18% and Seismic 3512 at 19%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
