It is 21' 8" long and 123" high with the air conditioner, with 20 gal fresh, 26 gal grey and 26 gal black tanks. Fresh water weighs about 8.3 lb per US gallon, so a full fresh tank uses roughly 166 lb of the cargo capacity before anything else is loaded.

Every number on this page was read on 5 Nov 2026 from KZ’s own floorplan page for the Sportsmen Classic 170MB, whose floorplan drawing KZ labels 2027. KZ notes that its UVW reflects a rolling average for the model and that your trailer will vary with optional equipment.
