I bough the Rv in October of 2006 this Rv is well built we average about 3,200 miles a year have the same axles that came with the trailer other than just maintenance just one problem is with the track for the rear slide out on the inside of the rv was an on going problem but not a big deal just about everything is the same equipment even the water pump and hot water heater and the fridge all in perfect working condition. I will buy a KZ in the future as long as quality does not suffer over profits so far I have never seen any complaints about KZ issues other than very minor issues about KZ RV’s Show less
