Two common diesel engine manuf, CAT or Cummins. Both are dependable.
Mileage on a DP is a less sensitive factor than condition of the House and the maintenance record history of the chassis. Do not limit yourself to low mileage DP candidates.
There are entry level DP units that do not provide air suspension and high end coaches that have electronic shades and all kinds of creature comforts.
High end older rigs with fewer slides may be more appealing at a price point than newer multi slide middle of the road offerings.
Take some time to learn the line up hierarchy of the manufacturers so that you can apply on line visual experiences to price points as you educate yourselves.
My preference is for a DP that has air leveling, and a side radiator but we do not have slides. Many owners are happy without my preferences but require 4 slides.
Only you can sort the factors in priority order.
Edit: But your target rig above shows you have them in order.
