What 32 ft 10 in buys in the 303RLS
Every other 2026 Reflection fifth wheel runs at least 34 ft 9 in, and the next one up, the 320MKS, is 1 ft 11 in longer and 1,000 lb heavier. The 303RLS is first of eight on length, on dry weight at 10,100 lb, and on hitch weight at 1,980 lb. On a 40-foot site it leaves 7 ft 2 in spare, and it is 8 ft 3 in shorter than the longest Reflection, the 367BHS. Its brochure height of 12 ft 3 in sits 1 ft 3 in under a 13 ft 6 in clearance, the most headroom of the family; the 311BHS is next lowest at 12 ft 11 in.
Grand Design does not shrink the rear living room to get there. The drawing puts a tri-fold sofa across the rear wall, a 40-inch entertainment center, pantry, microwave over the range, and a 16-cubic-foot refrigerator in the off-door slide, and theater seating with a booth dinette (a swivel dinette is optional) in the slide opposite. A kitchen island with the sink stands between the two slides. The bath is mid-ship, and the front bedroom holds a 60-by-80-inch queen set lengthwise with its head at the front wall, a wardrobe in a small slide, and TV prep.

Four 303RLS checks, walked from the rear sofa forward
- Sit on the rear tri-fold sofa, then in the theater seating, and look for the 40-inch screen from each. The drawing puts the entertainment center at the rear end of the off-door slide, beside the sofa and across from the theater seats, so the sight line differs by seat.
- Bring both living-room slides in and walk from the entry to the refrigerator and the bath. The island stands between the slides, and that travel-mode aisle is the route you will use at every fuel stop.
- In the front bedroom, open the wardrobe slide and decide where laundry goes. The 303RLS drawing carries no washer/dryer prep label; the 337RLS drawing, on a trailer 2 ft 9 in longer, marks one at the front wall.
- Look at the roof of the unit on the lot. Grand Design footnotes that its listed heights leave out a second air conditioner, so the 1 ft 3 in of margin under 13 ft 6 in applies only to a single-unit roof. Measure if a second one is fitted.
Three Reflections that answer what the 303RLS leaves out
Picked for what each changes about the layout. Differences are arithmetic from the 2026 brochure figures.
The rear half carries the same labels: tri-fold sofa, theater seating, booth dinette, island. It adds 2 ft 9 in, 1,100 lb of dry weight, and 320 lb of hitch, and the queen moves into an off-door slide with a king option and washer/dryer prep. Gray and black each shrink by 8 gal, to 79 and 39.
Open record →Kitchen at the back insteadReflection 320MKSThe refrigerator goes to the rear wall and the living room moves forward beside the entry, with an outside griddle and a 1.6-cubic-foot refrigerator added. It is 1 ft 11 in longer and 1,000 lb heavier, and hitch weight rises by 220 lb to 2,200 lb.
Open record →Bunks for 20 lb more hitchReflection 324MBSAdds a mid-ship slide with a 36-inch flip-top bunk over a 44-inch bottom bunk and a 92-inch U-shaped lounge at the rear. It is 4 ft 2 in longer and 1,100 lb heavier, yet only 20 lb heavier on the hitch, which gives it the lowest pin share in the family at 17.9%.

Which year the 303RLS figures describe
Length, dry and hitch weight, height, tank sizes, and every room label on this page come from Grand Design's 2026 Reflection brochure, read again on 2026-09-26. The brochure marks its weights as the average of a standard build, measures length from hitch to rear, and states that its heights exclude a second air conditioner, so the labels on the actual unit govern. GVWR, sleeping capacity, and slide count in the table come from RVUSA's 2026 spec guide. Grand Design's current 303RLS page now describes the 2027 model and lists different weights; this record stays with the 2026 brochure.
