We have a 2009 X213, Jayco went with the king bed in 2010.
We put 2 full size bikes in the lower bunk area and a third smaller bike would probably fit.
The sewer hose has its own compartment on the driver side in front of the bike door.We got a "starter kit" that came in a 5 gallon bucket. The water hoses get coiled up small enough to fit in the bucket.
The extra extension cords go on the floor around the bike tires.
Two big man lawn chairs ( not Bag chairs) fit in as well.
The storage area is somewhat deceiving as it goes toward the rear under the wardrobe. I keep the camp stove,tool box, stabilizer crank, an axe, and some other stuff in there.
It is usually just the two of us, unless one of our sons joins us for the weekend, then we just move the bikes out and drop the bottom bunk.
All the small stuff stays on the floor under the bunk.
There is some storage also under the dinette seats. Half of each side. Front side has water pump back side has water heater.
"SHE" likes the trailer due to more space to move around and the sofa.
I like the camper because I can put it into places the trailer isn't going to fit.
