01 What makes the 2019 4116 different
The Seismic 4116 is one of Jayco's Seismic fifth-wheel toy haulers, the flagship of the Seismic range, built around a rear garage behind the living space. This page covers one model year of it — the 2019 4116, exactly as Jayco published it — because the numbers that decide whether your truck can pull this trailer are not the same from one year to the next.
For the 2019 model year Jayco published a 20,695-pound GVWR on a 15,415-pound dry weight, 5,280 pounds of published cargo capacity, a 3,965-pound dry pin weight. A pin weight in that range lands well outside half-ton territory: plan on a three-quarter-ton or larger truck, and check the loaded pin against the truck's payload and rear-axle ratings rather than against the tow rating alone.
This is the earliest 4116 model year with a verified factory record in this catalogue. Later years are linked at the foot of the page, each with its own published figures.
A 2019 coach is 7 model years old as of 2026, which puts it squarely in used-buyer territory. Section 05 sets out what to inspect on a laminated-wall fifth wheel of this age — tyre date codes, roof and seam sealant, slide seals, and the soft-floor and delamination checks that separate a tidy coach from an expensive one.
Specifications by model year
2019 is the only model year this catalogue holds a verified factory record for the 4116. That record is published here on its own, and it is not a general specification for the floorplan: Jayco revises published weights, ratings and even tire sizes from one model year to the next, so every figure below is evidence about 2019 and about no other year.
| Model year | Dry (UVW) | GVWR | Cargo (CCC) | Dry pin | Sleeps | Tire size |
|---|---|---|---|---|---|---|
| 2019 | 15,415 | 20,695 | 5,280 | 3,965 | Not published | Not published |
The row above is the 2019 model year’s own record from Jayco’s model page for that year. When a second model year is sourced for this floorplan, it joins the table above on this same page and at this same address — nothing moves and no link breaks. The figures in the tow-critical placard at the top of this page are that same 2019 record. On the weights, overall length and tire size, that record and Jayco’s own 2019 model page agree on every field both of them publish. Exterior height is not compared: Jayco publishes a bare height, a with-A/C height and a with-2nd-A/C height, and the single height row carried here cannot be matched to one of them, so no claim is made either way.

Towing it
Loaded range: 15–25% of GVWR on the pin, a rule of thumb, not a measurement of this unit. No truck ratings or hitch classes (why; NHTSA, DOT HS 809 433). The range starts at the published dry figure, because loaded is never lighter than dry.
04 Buying a 2019 4116 at 7 model years old
Tyres are almost certainly past their service age
At 7 years old, the original the factory tire size will be well beyond the five-to-seven-year age window RV tyres are normally replaced on, regardless of tread depth. Budget for a full set plus the spare unless there is a dated receipt.
Water is what kills these, and it is the cheapest thing to check
Press the walls and floor around the entry, the slide openings, the rear wall and under the front cap. Soft spots, a wavy or rippled sidewall, or a stained ceiling are delamination and water ingress, and they are structural rather than cosmetic.
Appliance and component life
Absorption fridges, water heaters and A/C units commonly need attention somewhere in the second decade. Run every appliance on both gas and mains before agreeing a price.
Weigh it before you tow it
Every weight on this page is a DRY factory figure for the 2019 model year. A used coach carries its previous owner's additions, and a fifth wheel puts roughly 15-25% of the load through the truck's rear axle. Weigh the loaded rig at a public scale and check it against the truck's payload, rear-axle and hitch ratings.
05 How it compares
Every Seismic floorplan this catalogue holds a verified factory record for, with its own published weights.
06 Loading it for a trip
Cargo capacity on the 4116 is 5,280 lb.
07 Where this floorplan sits
Closest sibling: the Seismic 4114, nearest on the published figures. It differs on 4 of the 6 fields both publish (this plan first): length 43 ft 8 in vs 43 ft 7 in; dry weight 15,415 lb vs 15,800 lb; cargo capacity 5,280 lb vs 4,895 lb; dry hitch weight 3,965 lb vs 4,035 lb. They match on GVWR and black tank.

| Dry weight (lb) | 15,415 | 12 of 22 | 10,675–16,075 |
| Cargo capacity (lb) | 5,280 | 20 of 22 | 3,240–5,415 |

| Black tank (gal) | 87 | 7–20 of 20 | 50–87 |
Either side of it by GVWR: Seismic 4114 matches it at 20,695 lb GVWR; Seismic 4125 matches it at 20,695 lb GVWR.

11 NHTSA safety record
NHTSA holds 17 recall campaigns and 13 owner complaints against the Seismic line. They are counted separately: a recall is a confirmed defect with a remedy, a complaint one owner’s unverified account.
What to look at on a used one. Across the 13 complaints filed on this line the most-reported components are suspension (38%), unknown or other (23%) and service brakes (15%).
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 Seismic line page.
