2026 Coachmen Apex Nano203RBK

The Coachmen Apex Nano 203RBK leaves Coachmen's factory at 4,158 lbs dry, with a published GVWR of 6,000 lbs and 1,842 lbs of cargo capacity between the two. Cargo capacity is 31% 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 52-gallon fresh tank spends 432 lbs of that 1,842 lbs before anything else is loaded.

Tongue weight is 530 lbs, or 13% 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 52 gallons fresh, 35 grey and 35 black, 70 gallons of waste capacity against 52 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 Nano roster this is the 8th of 13 floorplans by dry weight, in a line that runs from 3,420 lbs to 4,632 lbs. It sits in the middle of the line by weight. 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 4,158 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 5,079 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 6,000 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. 203RBK is a Coachmen Apex Nano designation and this site does not decode it into a layout claim.

How the 203RBK differs from the other twelve Coachmen Apex Nano floorplans. Most distinctive first. Each rank counts only the siblings that publish that field, and a figure most of them share is left out.

• Cargo capacity, 1,842 lb: largest of thirteen; next is the 213RDS (1,790 lb).
• Cargo capacity as a share of GVWR, 30.7%: largest of thirteen; next is the 213RDS (29.8%).
• Dry weight, 4,158 lb: sixth-heaviest of thirteen, between the 194BHS (3,938 lb) and the 213RDS (4,210 lb).
• Tongue weight, 530 lb: sixth-lightest of thirteen, between the 183BH and 186BH (497 lb) and the 228BHS (536 lb).
• Length, 23 ft 5 in: sixth-longest of thirteen, between the 183BH and 186BH (22 ft 11 in) and the 208BHS (24 ft 11 in).
• GVWR, 6,000 lb: highest of thirteen, level with the 208BHS, 213RDS and three others; next are the 181RB, 183BH and five others (4,700 lb).
• Tongue weight as a share of dry weight, 12.7%: shared with the 181RB and 187RB; of thirteen, four smaller and six larger, nearest the 216RKS (12.5%) and the 183BH, 186BH and 208BHS (13.2%).
• Grey tank, 35 gal: shared with the 190RBS, 208BHS and two others; of thirteen, six smaller and two larger, nearest the 181RB, 183BH and four others (27 gal) and the 216RKS and 224RBS (70 gal).

Next to the 194BHS, the nearest lighter floorplan by dry weight, the 203RBK is 220 lb heavier by dry weight, has a GVWR 1,300 lb higher, has 1,080 lb more cargo capacity, has a tongue weight 24 lb lighter, is 9 in longer, has a grey tank 8 gal larger and has a black tank 8 gal larger; the two publish the same exterior height and fresh tank.

Next to the 213RDS, the nearest heavier floorplan by dry weight, the 203RBK is 52 lb lighter by dry weight, has 52 lb more cargo capacity, has a tongue weight 60 lb lighter and is 1 ft 9 in shorter; the two publish the same GVWR, exterior height, fresh tank, grey tank and black tank.

Apex Nano is the narrow, light end of the Apex family: every floorplan is 7.5 ft wide, against 8 ft for the Ultra-Lite and X-Series. The 13 plans in Coachmen's 2026 table run from 3,420 lb to 4,632 lb unloaded, on published hitch weights of 423 to 590 lb, and they carry one of only 2 GVWR figures between them: 4,700 lb and 6,000 lb. So the line splits cleanly into a lighter group rated 4,700 lb and a longer group rated 6,000 lb, and inside each group the plan with the higher unloaded weight has less cargo capacity left, because the rating does not move. Dry weight plus cargo capacity equals the published GVWR on 13 of 13.

A full 52-gallon fresh tank is about 434 lb of water (water counts as cargo: 49 CFR 571.110 S9.3.2), 24% of the 203RBK’s 1,842 lb cargo capacity, leaving 1,408 lb. Across 13 Coachmen Apex Nano floorplans the water share runs 24% to 57%, and this plan’s is the lowest. Nearest on that share: Coachmen Apex Nano 213RDS at 24%. 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 Nano 213RDS, nearest on the published figures. It differs on 4 of the 8 fields both publish (this plan first): length 23 ft 5 in vs 25 ft 2 in; dry weight 4,158 lb vs 4,210 lb; cargo capacity 1,842 lb vs 1,790 lb; hitch weight 530 lb vs 590 lb. They match on GVWR, fresh tank, grey tank and black tank.

Either side of it by GVWR: Coachmen Apex Nano 194BHS is 1,300 lb lighter (4,700 lb GVWR); Coachmen Apex Nano 208BHS matches it at 6,000 lb GVWR.
