Which may or may not be possible in this model. I have the smaller model to this, the X213 and due to the rear slide, there isn't a lot of space to load gear in the rear. And it's not practical to store all of your kitchen, bathroom and front wardrobe clothing under the dinette and have to shift it all and load cabinets once you arrive.
The tongue on the X213 is heavy. There is no way I could get it below 600 pounds if I had to. Trust me, I had to and couldn't do it. Our tongue is over 700 pounds; 771 with bikes, somewhere around 720 without bikes.
Also, that x254 is going to weight closer to 5000 pounds once it arrives with all options. And will be close to 6000 once loaded. So you're tongue minimum will be 600 pounds assuming the trailer will even allow you to pack it to keep it at 600. But consider the tongue could be up to around 900 pounds.
