2405 Length Behind Truck

[Potnah]

I'm currently shopping for a good camper/truck setup that isn't too long so I can fit in as many places as possible. I'm quite intrigued by the micro minnie 2405s as they are a 5th wheel, which provides more interior space with less length behind the truck. I see on the manufacturer's website that the external length of the trailer is 26'9", but I can't find anywhere how long the trailer is expected to extend past the rear bumper. Does anyone have an idea? I'm trying my best to find a combo that works with providing as much flexibility to take advantage of national park restrictions.

Thanks in advance!
