01 What makes it unique
KZ lists the 2008 New Vision Sportster 40P at 13,965 lb dry, a GVWR of 18,000 lb, a net carrying capacity of 4,035 lb and a hitch weight of 2,978 lb. Its dry weight plus its carrying capacity comes to exactly its GVWR.
It is 42'5" long and 13'1" high. KZ prints its tanks as 110 gal fresh, 50 gal grey, 50 gal black.
Among the 7 New Vision Sportster floorplans KZ’s New Vision Sportster brochure (filed in KZ’s 2008 brochure folder; the brochure prints no year) lists with a published dry weight, it is number 4 from the lightest, in a range from 13,420 lb (New Vision Sportster 38SB) to 14,265 lb (New Vision Sportster 41KG). Every figure in that comparison is KZ’s, for the same model year.
Every number on this page was read on 5 Nov 2026 from KZ’s New Vision Sportster 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 40P differs from the other six New Vision Sportster floorplans. Most distinctive first. How these ranks are worked out.
- Cargo capacity, 4,035 lb: third-largest of seven, between the 41K and 41RL (4,015 lb) and the 38P (4,350 lb).
- Cargo capacity as a share of GVWR, 22.4%: third-largest of seven, between the 41K and 41RL (22.3%) and the 38P (24.2%).
- Dry weight, 13,965 lb: fourth-lightest of seven, between the 38P (13,650 lb) and the 41K and 41RL (13,985 lb).
- Length, 42 ft 5 in: shared with the 41K and 41RL; of seven, three shorter and one longer, nearest the 38P (40 ft 5 in) and the 41KG (43 ft 5 in).
Next to the 38P, the nearest lighter floorplan by dry weight, the 40P is 315 lb heavier by dry weight, has 315 lb less cargo capacity and is 2 ft longer; the two publish the same GVWR, exterior height, fresh tank, grey tank and black tank.
Next to the 41K, the nearest heavier floorplan by dry weight, the 40P is 20 lb lighter by dry weight and has 20 lb more cargo capacity; the two publish the same GVWR, length, exterior height, fresh tank, grey tank and black tank.

04 Notes on this floorplan
What KZ does not publish for the New Vision Sportster 40P
KZ prints no interior height, 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
13,650 lb dry and 18,000 lb GVWR, against this model’s 13,965 lb and 18,000 lb.
13,985 lb dry and 18,000 lb GVWR, against this model’s 13,965 lb and 18,000 lb.
06 Loading it for a trip
A full 110-gallon fresh tank is about 913 lb of water (water counts as cargo: 49 CFR 571.120 S10.4.2), 23% of the New Vision Sportster 40P’s 4,035 lb cargo capacity, leaving 3,122 lb. Across 7 New Vision Sportster floorplans the water share runs 20% to 26%, and 4 give up more than this one. Nearest on that share: New Vision Sportster 38P at 21% and New Vision Sportster 41K at 23%. Your own unit’s figure is on the label inside its entry door (49 CFR 571.120 S10.4.3).
No source publishes a tongue weight for the New Vision Sportster 40P, so its hitch load has to come from a scale ticket taken with the trailer hitched.
07 Where this floorplan sits
Closest sibling: the New Vision Sportster 41K, nearest on the published figures. It differs on 2 of the 7 fields both publish (this plan first): dry weight 13,965 lb vs 13,985 lb; cargo capacity 4,035 lb vs 4,015 lb. They match on length, GVWR, fresh tank, grey tank and black tank.
