Jayco Jay Flight SLX · 2019–2020235RKS

The Jay Flight SLX 235RKS is one of Jayco's Jay Flight SLX travel trailers, the lighter value tier of Jayco’s Jay Flight nameplate. This page covers one model year of it — the 2020 235RKS, 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 2020 model year Jayco published a 7,000-pound GVWR on a 5,505-pound dry weight, 1,495 pounds of published cargo capacity, a 550-pound dry tongue weight. That dry tongue is 10% of the dry weight, below the 10–15% band conventionally quoted for a bumper-pull trailer. Tongue weight is not fixed — it moves with how the trailer is loaded, and weight added ahead of the axles raises it. Check the loaded tongue against the hitch receiver's rating and the tow vehicle's payload rather than against the tow rating alone.

Against the 2019 build of the same floorplan, 4 published fields moved. The full comparison is in section 02, and it is drawn from two separate verified factory records rather than from one record and an assumption about the other.

A 2020 trailer is 6 model years old as of 2026, which puts it squarely in used-buyer territory. Section 05 sets out what to inspect on a travel trailer 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.

How the 235RKS differs from the other 35 Jay Flight SLX floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out. Not every one of these pages covers the same model years as this one (2019–2020); each figure is the one its own page prints, so a rank compares pages, not one model year.

• Sleeping capacity, 2: smallest of eighteen, level with the 237RBS; next are the 145RB and 280FKS (3).
• Dry tongue weight as a share of dry weight, 10%: shared with the 195RB; of 36, three smaller and 31 larger, nearest the 183RBW (9.9%) and the 174BHW (10.1%).
• Grey tank, 78 gal: shared with the 237RBS, 265BHS and 286BHSW; of 36, 30 smaller and two larger, nearest the 294QBS (47.5 gal) and the 290RKS (110.5 gal).
• Cargo capacity, 1,495 lb: thirteenth-largest of 35, between the 267BHS (1,400 lb) and the 242BHS (1,595 lb).
• Dry weight, 5,505 lb: fifteenth-heaviest of 36, between the 242BHS (5,405 lb) and the 244BHS (5,535 lb).
• Cargo capacity as a share of GVWR, 21.4%: shared with the 280FKS; of 35, ten smaller and 23 larger, nearest the 145RB (20.5%) and the 294QBS (21.5%).
• Dry tongue weight, 550 lb: eighteenth-lightest of 36, between the 211MB (505 lb) and the 298BH (555 lb).

• GVWR, 7,000 lb: shared with the 242BHS, 245RLS and two others; of 36, twenty lower and eleven higher, nearest the 244BHS (6,750 lb) and the 265BHSW (7,600 lb).
• Fresh tank, 44 gal: shared with the 242BHS, 244BHS and four others; of 35, twelve smaller and sixteen larger, nearest the 298BH (42 gal) and the 237RBS and 324BDS (46 gal).

Next to the 242BHS (2018 page), the nearest lighter floorplan by dry weight, the 235RKS is 100 lb heavier by dry weight, has 100 lb less cargo capacity, has a dry tongue weight 70 lb lighter, is 1 ft 3 in shorter and has a grey tank 39 gal larger; the two publish the same GVWR, interior height and fresh tank.

Next to the 244BHS (2018 page), the nearest heavier floorplan by dry weight, the 235RKS is 30 lb lighter by dry weight, has a GVWR 250 lb higher, has 280 lb more cargo capacity, has a dry tongue weight 95 lb lighter, is 9 in shorter and has a grey tank 39 gal larger; the two publish the same interior height and fresh tank.

This floorplan has a published factory record for 2 model years here, 2019 to 2020. The specification does not hold still: dry weight runs from 5,470 lb (2019) to 5,505 lb (2020); dry tongue weight runs from 550 lb (2020) to 555 lb (2019). 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.

Jayco changed 4 of the published fields between the 2019 and 2020 235RKS. Every figure in both columns is that model year's own factory record — nothing here is carried across from the other year.

A full 44-gallon fresh tank is about 367 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 25% of the 235RKS’s 1,495 lb cargo capacity, leaving 1,128 lb (564 lb per rated berth). Across 34 Jay Flight SLX floorplans the water share runs 18% to 39%, and 18 give up more than this one. Nearest on that share: Jay Flight SLX 211MB at 24% and Jay Flight SLX 287BHS at 25%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).

Closest sibling: the Jay Flight SLX 237RBS, nearest on the published figures. It differs on 6 of the 9 fields both publish (this plan first): length 27 ft 11 in vs 26 ft 8 in; dry weight 5,505 lb vs 5,380 lb; GVWR 7,000 lb vs 6,500 lb; cargo capacity 1,495 lb vs 1,120 lb; hitch weight 550 lb vs 598 lb; fresh tank 44 gal vs 46 gal. They match on sleeps, grey tank and black tank.

Either side of it by GVWR: Jay Flight SLX 244BHS is 250 lb lighter (6,750 lb GVWR); Jay Flight SLX 242BHS matches it at 7,000 lb GVWR.
