01 What makes it unique
KZ lists the 2008 Montego Bay 34 RLB-3 at 11,877 lb dry, a GVWR of 16,000 lb, a net carrying capacity of 4,123 lb and a pin weight of 2,285 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 37' 3" long and 153" high. KZ prints its tanks as 55 gal fresh, 50 gal grey, 50 gal black.
Among the 5 Montego Bay floorplans KZ’s Montego Bay brochure (filed in KZ’s 2008 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 2 from the lightest, in a range from 11,677 lb (Montego Bay 30 KSB-3) to 12,397 lb (Montego Bay 36 REB-3). Every figure in that comparison is KZ’s, for the same model year.
Every number on this page was read on 6 Nov 2026 from KZ’s Montego Bay brochure (filed in KZ’s 2008 brochure folder; the brochure prints no year); model year 2008 comes from where the maker files it on its own site, not from the document’s text.
How the RLB-3 differs from the other four Montego Bay floorplans. Most distinctive first. How these ranks are worked out.
- Dry weight, 11,877 lb: second-lightest of five, between the KSB-3 (11,677 lb) and the 34-SB-3 (11,927 lb).
- Cargo capacity, 4,123 lb: second-largest of five, between the 34-SB-3 (4,073 lb) and the KSB-3 (4,323 lb).
- Cargo capacity as a share of GVWR, 25.8%: second-largest of five, between the 34-SB-3 (25.5%) and the KSB-3 (27%).
- Pin weight, 2,285 lb: second-lightest of five, between the IKB-3 (2,232 lb) and the REB-3 (2,312 lb).
- Pin weight as a share of dry weight, 19.2%: third-smallest of five, between the REB-3 (18.6%) and the 34-SB-3 (20.9%).
- Length, 37 ft 3 in: third-shortest of five, between the 34-SB-3 (37 ft) and the IKB-3 (37 ft 4 in).
Next to the KSB-3, the nearest lighter floorplan by dry weight, the RLB-3 is 200 lb heavier by dry weight, has 200 lb less cargo capacity, has a pin weight 165 lb lighter and is 2 ft 1 in longer; the two publish the same GVWR, exterior height, interior height, fresh tank, grey tank and black tank.
Next to the 34-SB-3, the nearest heavier floorplan by dry weight, the RLB-3 is 50 lb lighter by dry weight, has 50 lb more cargo capacity, has a pin weight 207 lb lighter and is 3 in longer; the two publish the same GVWR, exterior height, interior height, fresh tank, grey tank and black tank.

Towing it
Check your vehicle. Enter the ratings from your owner’s manual and the door-pillar placard.
Compares your figures with this page’s published GVWR (16,000 lb) and the upper loaded pin estimate (4,000 lb, a rule of thumb). Your vehicle’s placard and the trailer’s own weight label govern.
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).

04 Notes on this floorplan
What KZ does not publish for the Montego Bay 34 RLB-3
KZ prints no sleeping capacity for this model, so none is given. Nothing is filled from a sibling model, a different model year or a dealer listing.
Read the label on the trailer
Federal rules put a load-carrying label inside every RV trailer: its unloaded weight with full propane, its cargo carrying capacity and its GVWR (49 CFR 571.110 and 571.120). Those figures come from the trailer itself and govern the towing decision.
05 How it compares
11,677 lb dry and 16,000 lb GVWR, against this model’s 11,877 lb and 16,000 lb.
11,927 lb dry and 16,000 lb GVWR, against this model’s 11,877 lb and 16,000 lb.
06 Loading it for a trip
A full 55-gallon fresh tank is about 457 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 11% of the Montego Bay 34 RLB-3’s 4,123 lb cargo capacity, leaving 3,666 lb. Across 5 Montego Bay floorplans the water share runs 11% to 13%, and 3 give up more than this one. Nearest on that share: Montego Bay 30 KSB-3 at 11% and Montego Bay 34-SB-3 at 11%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
07 Where this floorplan sits
Closest sibling: the Montego Bay 36 IKB-3, nearest on the published figures. It differs on 4 of the 8 fields both publish (this plan first): length 37 ft 3 in vs 37 ft 4 in; dry weight 11,877 lb vs 12,067 lb; cargo capacity 4,123 lb vs 3,933 lb; hitch weight 2,285 lb vs 2,232 lb. They match on GVWR, fresh tank, grey tank and black tank.

11 NHTSA safety record
NHTSA holds 5 recall campaigns and 3 owner complaints (model years 2005 on) against the Montego Bay line (a recall and a complaint are not the same thing).
Too few reports to show a pattern. 3 complaints have been filed on this line — not enough to say what fails most often. They cover tires and latches/locks/linkages.
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 Montego Bay line page.
