2026 Coachmen Apex Ultra-Lite X-Series24RBX

The Coachmen Apex Ultra-Lite X-Series 24RBX leaves Coachmen's factory at 5,507 lbs dry, with a published GVWR of 7,000 lbs and 1,493 lbs of cargo capacity between the two. Cargo capacity is 21% of the loaded rating, and cargo capacity is what remains for fresh water, gear, food, batteries and every dealer-installed accessory. Fresh water alone is 8.3 lb per gallon, so filling this trailer's 50-gallon fresh tank spends 415 lbs of that 1,493 lbs before anything else is loaded.

Tongue weight is 614 lbs, or 11% of the dry weight. Ten to fifteen percent is the conventional band for a bumper-pull trailer, and this plan sits inside it as published. Tongue weight is not fixed: it moves with how the trailer is loaded, and weight added ahead of the axles raises it. A weight-distribution hitch is the normal fitment at this tongue load, and the tow vehicle's tongue-weight limit is a separate number from its trailer-weight limit.

Tank capacities are 50 gallons fresh, 35 grey and 35 black, 70 gallons of waste capacity against 50 gallons of supply. The ratio is what governs how long the trailer can sit off hookups: waste capacity exceeds fresh, so the fresh tank is the binding constraint and refilling extends the stay. Coachmen publishes these three figures per floorplan, and they are the factory's numbers rather than a segment average.

Against the rest of the Coachmen Apex Ultra-Lite X-Series roster this is the 1st of 3 floorplans by dry weight, in a line that runs from 5,507 lbs to 6,123 lbs. It is the lightest plan in the line, which makes it the one to look at first if the tow vehicle is the constraint. Comparing floorplans inside one line is more reliable than comparing across brands, because every figure here comes from the same factory channel on the same day.

A useful way to read the pair of weights is to stop planning against the dry figure. Nobody tows a trailer at 5,507 lbs: that is the weight before water, batteries, propane, bedding, food, tools and anything the dealer bolted on. Load half the published cargo capacity, which is modest for a family trip, and this plan is already near 6,253 lbs on the road. Compare that number against the tow vehicle, not the dry weight, and leave margin on top of it - the published GVWR of 7,000 lbs is a limit rather than a target.

Every number above was read from one factory document: Coachmen's own 2026 brochure for this line, and each figure was read back against that document's text before it was published. This is a single-channel record rather than the two-page cross-check this site runs on saved factory web pages, and it is described that way rather than dressed up as more. Dry weight plus cargo capacity also equals the published GVWR exactly, which is the arithmetic check this site runs on every profiled floorplan. Where a figure is missing from this page it is because the brochure does not publish it, not because it was hard to find - and the row says so rather than being quietly dropped.

Coachmen publishes no floorplan description for this plan in the channel this page is built from - only the numeric specification block. Rather than describe a layout from the floorplan code, which would be a guess dressed as a fact, this page carries what the factory publishes and says where it stops. 24RBX is a Coachmen Apex Ultra-Lite X-Series designation and this site does not decode it into a layout claim.

How the 24RBX differs from the other two Coachmen Apex Ultra-Lite X-Series floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.

• Dry weight, 5,507 lb: lightest of three; next is the 26BHX (5,773 lb).
• GVWR, 7,000 lb: lowest of three; next is the 26BHX (7,350 lb).
• Cargo capacity, 1,493 lb: smallest of three; next is the 26BHX (1,577 lb).
• Cargo capacity as a share of GVWR, 21.3%: smallest of three; next is the 26BHX (21.5%).
• Tongue weight, 614 lb: lightest of three; next is the 26BHX (730 lb).
• Tongue weight as a share of dry weight, 11.1%: smallest of three; next is the 26BHX (12.6%).
• Length, 29 ft 1 in: shortest of three; next is the 26BHX (30 ft 11 in).

Next to the 26BHX, the nearest heavier floorplan by dry weight, the 24RBX is 266 lb lighter by dry weight, has a GVWR 350 lb lower, has 84 lb less cargo capacity, has a tongue weight 116 lb lighter and is 1 ft 10 in shorter; the two publish the same exterior height, fresh tank, grey tank and black tank.

The X-Series is a three-floorplan group Coachmen publishes in its own table beside the Apex Ultra-Lite, 8 ft wide, running 5,507 to 6,123 lb unloaded on hitch weights of 614 to 884 lb. Its standards page differs from the Ultra-Lite's in ways the brochure prints: a wood truss roof with a Tufflex membrane and steel rims on the X-Series, against a laminated aluminum trussed roof and aluminum rims on the Ultra-Lite. Dry weight plus cargo capacity equals the published GVWR on 3 of 3.

A full 50-gallon fresh tank is about 417 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 28% of the 24RBX’s 1,493 lb cargo capacity, leaving 1,076 lb. Across 3 Coachmen Apex Ultra-Lite X-Series floorplans the water share runs 24% to 28%, and this plan’s is the highest. Nearest on that share: Coachmen Apex Ultra-Lite X-Series 26BHX at 26%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.110 S9.3.3).

Closest sibling: the Coachmen Apex Ultra-Lite X-Series 26BHX, nearest on the published figures. It differs on 5 of the 8 fields both publish (this plan first): length 29 ft 1 in vs 30 ft 11 in; dry weight 5,507 lb vs 5,773 lb; GVWR 7,000 lb vs 7,350 lb; cargo capacity 1,493 lb vs 1,577 lb; hitch weight 614 lb vs 730 lb. They match on fresh tank, grey tank and black tank.

Either side of it by GVWR: Coachmen Apex Ultra-Lite X-Series 26BHX is 350 lb heavier (7,350 lb GVWR).
