We bought this unit new a year ago. It has been on one 10 day trip!  It is virtually brand new. We bought some land to build a new house on so this has to go. 
It has a few upgrades that other 28DK5s don’t have. I added app controlled slides and leveling. The one control app also monitors the propane level and battery levels. 
I added strong arm stabilizer arms to the front landing gear. And I added an additional sewer hose storage tube under the camper near the dump outlet. 
It has solar panels on the roof and the Yamaha 5500 generator on board. It has no problem running the 2 ac units. If you are looking for a versatile toy hauler this is your unit. 
We are asking $60500 OBO. 
We are located near Kansas City
