01 What makes it unique
The Jayco Jay Flight Bungalow 401FLTS is a 40' 4" destination trailer in the MY2027 Jay Flight Bungalow roster. Jayco publishes a dry weight of 10,355 pounds against a 12,000-pound GVWR, and the two tie out exactly with the published 1,645-pound cargo carrying capacity — 10,355 + 1,645 = 12,000. 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 tongue weight is 1,515 pounds, or 15% of the dry weight. Tongue load transfers to the hitch and the rear axle, and a weight-distributing hitch redistributes it rather than removing it. Payload is 1,645 pounds, 14% of GVWR — that is the ceiling for water, propane, cargo and any dealer-fitted equipment combined. Fresh water alone at 52 gallons is about 434 pounds when full.
Tanks are 52 gallons fresh, 39 grey and 39 black. Interior height is 8' 0" and the exterior measures 8' 0" wide. Jayco publishes two exterior heights for this floorplan: 12' 0" at the roofline and 12' 7" 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. This page covers the MY2027 401FLTS only. Jayco’s figures move between model years — measured on one Jayco floorplan across five consecutive years, 20 of 28 published fields changed, including a 290-pound swing in dry hitch weight — so nothing here is carried over from a neighbouring year, and no year is shown that Jayco has not published for this code.

These graphics are generated from the same verified record that builds the table above, and are published under this site’s own licence — nothing here is traced from, or derived from, a manufacturer drawing or photo. Where a figure is not published for this plan, the graphic that would need it is omitted rather than estimated. The full record is in the published dataset.
What it takes to tow this
Built from this floorplan’s verified weights. We publish the trailer side only.
We do not publish tow ratings for specific trucks. A single model can vary by thousands of pounds depending on engine, axle ratio, cab, drivetrain and package — the only authoritative figure is the one on your own door jamb. Loaded tongue percentages are industry convention for travel trailers (10–15% of loaded weight), not a measurement of this unit. Hitch classes are not used here as a rating: SAE J684 covers trailers to 10,000 lb GVWR and does not define Class V, and capacity boundaries differ between manufacturers — read the rating stamped on your hitch. On this plan the convention band’s low end fell below the published dry figure, so the range starts at the published dry weight instead — loaded is never lighter than dry.
03 The Jay Flight Bungalow floorplan family
Jay Flight Bungalow is Jayco's destination-trailer roster inside the Jay Flight family — forty-foot-plus units built to be towed to a seasonal site and left there. Jayco's own floorplan index titles the roster a spacious destination travel trailer. It is a factory sub-roster of Jay Flight and is catalogued under the Jay Flight line hub. The 401FLTS on this page is highlighted; every other profiled plan links to its own page.
| Floorplan | Family | Type | Nominal | Sleeps | Notable |
|---|---|---|---|---|---|
| 401FLTS | 2027 | TT | 40 ft | 4 | 40' 4" · 8' 0" interior · sleeps 4 |
| 401LOFT | 2027 | TT | 42 ft | 8 | 42' 0" · 8' 10" interior · sleeps 8 |
| 404LOFT | 2027 | TT | 42 ft | 8 | 42' 0" · 8' 11" interior · sleeps 8 |

04 What owners & reviewers report
Figures are Jayco’s own, and they tie out
Dry 10,355 lb + cargo 1,645 lb = GVWR 12,000 lb exactly. Nothing on this page is computed from the other two, estimated from the segment, or taken from a dealer listing.
Dry means empty, and you will not tow it empty
10,355 lb is the unit as built, before water, propane, batteries, cargo or dealer-installed options. Weigh the loaded trailer on a public scale before matching it to a tow vehicle.
Tongue load rides the rear axle
1,515 lb dry tongue transfers to the hitch and the rear axle. A weight-distributing hitch moves that load around; it does not make it disappear.
This is a destination trailer, and it tows like one
Jayco markets Bungalow for seasonal placement rather than touring. At this length and weight it is a heavy-duty tow even empty, many campgrounds cap the length they will take, and a unit left on a site still has to be moved twice a year. Check the site’s own length limit and your tow vehicle’s rating before committing.
What this page does not publish
Jayco’s factory spec table for this floorplan carries no slide count, no bed size, no refrigerator or air-conditioner spec, no tire size and no MSRP. Those rows are absent here rather than filled from a sibling floorplan or a second source. Jayco’s published awning length is held in this catalogue’s capture but not printed, because the catalogue tracks no awning field to print it into.
05 How it compares
Dry 11,575 lb against this plan’s 10,355 lb — 1,220 lb more to tow.
Every Jay Flight Bungalow floorplan catalogued here, with the plans this site refuses to publish and the reason for each.
06 Loading it for a trip
This floorplan carries its water comfortably. A full 52-gallon fresh tank is roughly 26% of the 1,645-pound cargo capacity, leaving the 401FLTS with a usable gear budget even when you tow full.
| Weight budget | Figure | What it means |
|---|---|---|
| Cargo capacity as published (CCC) | 1,645 lb | Everything you add: gear, water, propane, batteries, food, people’s belongings. |
| Fresh tank filled (52 gal × 8.34 lb) | −434 lb | Water is the heaviest thing most owners add, and it is added first. |
| Cargo budget left with a full fresh tank | 1,211 lb | 26% of this plan’s capacity is spent before a single bag is loaded. |
| Per sleeping position, water aboard | 303 lb | A rough share of what is left across the 4 berths this plan sleeps. |
The published dry tongue weight of 1,515 pounds is 15% of the 10,355-pound dry weight, which sits inside the 10–15% band usually quoted for stable towing. It is still a dry figure: loading the front pass-through and the fresh tank both push it up.
Nothing above changes the ceiling. Loaded to its 12,000-pound GVWR the 401FLTS is towing 1,645 pounds more than its 10,355-pound dry figure, and that is the number your vehicle has to be rated for — not the brochure weight.
Tank balance is generous here: 52 gallons of fresh against 39 grey and 39 black, so waste capacity keeps pace with supply and the fresh tank is the constraint that ends a dry stay.
07 Where this floorplan sits
Ranked by GVWR, the 401FLTS sits 109 of 117 in the Jay Flight line: 12,000 pounds against a line that runs from 3,500 to 14,500 pounds. That position is the useful thing to know, because the plans immediately either side of it are the real alternatives.
Either side of it in the same line: Jay Flight 34RLOK is 650 pounds lighter at 11,350 lb GVWR; and Jay Flight 40FKDS is 1,000 pounds heavier at 13,000 lb GVWR.
| Comparable travel trailers | GVWR (lb) | Dry (lb) | Sleeps | Length |
|---|---|---|---|---|
| 401FLTS | 12,000 | 10,355 | 4 | 40 ft 4 in |
| Puma Vista 39DBT | 12,000 | 10,162 | — | 42 ft 4 in |
| Eagle 312BHOK | 11,995 | 10,015 | 8 | 38 ft 8 in |
| Reflection 345RLTS | 11,995 | 10,275 | 6 | 38 ft 10 in |
| Cherokee Timberwolf 27MDK | 11,924 | 10,124 | — | 35 ft 11 in |
| Cyclone 2214 | 11,700 | 7,445 | 4 | 28 ft 1 in |
| Seismic 214 | 11,700 | 7,445 | 6 | — |
Against the 401FLTS: the Puma Vista 39DBT is 2 ft longer; the Eagle 312BHOK is 5 lb lighter and 2 ft shorter and sleeps 4 more; the Reflection 345RLTS is 5 lb lighter and 2 ft shorter and sleeps 2 more. Those are differences in the published numbers only — what they cost, how they are built and how they live are separate questions each of those pages answers on its own terms.
Those are the nearest travel trailers from other lines by weight — one per line, picked by proximity on that figure and nothing else. They are listed so the same tow vehicle can be checked against real alternatives, not because they are equivalent inside; layout, build and price diverge sharply across that group.
For scale, the Jay Flight floorplans profiled here run 2,450 to 12,430 pounds dry and 16 to 42 feet of exterior length across 117 plans. Where a floorplan falls in that spread usually says more about which vehicle can tow it, and which site it fits, than the layout name does.

08 Common questions about the 401FLTS
How much does the 401FLTS weigh?
It leaves the factory at 10,355 pounds dry, and its manufacturer-set loaded ceiling (GVWR) is 12,000 pounds. Real towing weight lands between the two and depends entirely on what you load. Use the GVWR when matching a tow vehicle; the dry figure is only useful for comparing floorplans against each other.
How much can the 401FLTS carry?
Cargo carrying capacity is 1,645 pounds. That is the whole budget: water, propane, batteries, gear and everything you bring. Filling the 52-gallon fresh tank uses about 434 pounds of that.
What is the tongue weight of the 401FLTS?
The published dry tongue weight is 1,515 pounds. It is measured empty; loaded, it runs higher, and it comes out of your tow vehicle’s payload rather than its tow rating.
What size tow vehicle does the 401FLTS need?
Your vehicle needs a tow rating of at least 12,000 pounds — this floorplan’s GVWR — and enough payload left over for the hitch load, passengers and anything in the bed. This site does not publish tow ratings for specific vehicles, because one truck model varies by thousands of pounds across engine, axle ratio, cab and package. The figure that governs is the payload sticker on your own door jamb.
How many people does the 401FLTS sleep?
It is rated to sleep 4. Rated sleeping positions include convertible furniture, so count the beds against how you actually travel rather than against the number.
What are the tank capacities on the 401FLTS?
Fresh 52 gallons, grey 39 gallons, black 39 gallons. Tank sizes set how long the floorplan can sit away from hookups, and the smallest of the three is what ends the stay.
How long is the 401FLTS?
Exterior length is 40' 4". Measure against your site length and your storage before committing — the exterior figure is the one that has to fit, and it includes the tongue or pin box.
Every figure in these answers is read from this page’s verified specification table. Where the manufacturer publishes nothing, the question is not answered rather than estimated.
09 What this page publishes, and what it does not
This catalog tracks 18 specification fields per floorplan. Named sources publish 12 of them for the 401FLTS. The rest are not shown, because the alternative is reading a figure across from a sibling floorplan or from what the segment usually does — and a number nobody published is worth less than an admitted gap.
Not published for this floorplan: slide count, axle count, tire specification, awning, refrigerator, air conditioning. If you find one of these in a manufacturer document for this plan, it belongs on this page.
The completeness figure at the foot of this page (100%) measures the same thing on the full field set: it is a measurement of how much this floorplan’s manufacturer publishes, not of how much research went into the page.
How every figure here was sourced and checked is set out on the methodology page.
11 NHTSA safety record
This floorplan belongs to the Jay Flight line, and NHTSA holds 25 recall campaigns and 80 owner complaints against that line. They are separate records and are not added together — a recall is a manufacturer-confirmed defect with a remedy; a complaint is one owner’s account, which NHTSA does not verify.
What to look at on a used one. Across the 80 complaints filed on this line the most-reported components are equipment (42%), unknown or other (12%) and structure (11%). That is where owners of this family have had trouble, so it is where an inspection is worth the time.
Recall coverage is not complete — our harvest of NHTSA’s recall API ran 1,556 queries, of which 0 failed and 242 returned an explicit zero. A line can still be under-reported where NHTSA files a roster under a parent name, or where a match rests on the wording of the recall rather than its model field. Complaints come from the complete bulk file but are unverified and self-selected: a high count tracks how many units a line sold at least as much as how well it was built. Check a specific VIN at NHTSA before you buy. Full tables are on the Jay Flight line page.
