I'm currently looking at some travel trailers with rear slide outs and trying to narrow based on length. I know the official measurements are typically hitch to bumper, but does anyone know how rear slides are accounted for? Are they typically still using hitch to bumper, or are they measuring with the slide out?
Thank you
Keystone defines length as: The distance from the centerline of the hitch pin/coupler to the rear bumper of the trailer.
So the rear slide is not considered in the brochure specifications for length.
Manufacturers usually list the hitch‑to‑bumper length only, and anything that slides out the back isn’t counted unless it’s fixed in place. I’ve measured a few units myself by comparing brochure numbers with a quick screen check using a ruler (online) https://ruler.onl, which helped me get real‑world lengths before driving out to see them. It makes it easier to know if a rear slide will push you past a storage limit
