Fred and Carolyn from Pa. We have a 2017 3791RD we have had this unit about 1 year now. After traveling to the west coast and back last winter I have had to replace the original tires which had about 7,000 miles on them. Just had installed Goodyear Endurance tires hope these last longer than the original ones. Love the unit but have had a number of things go bad, had to replace the toilet which Keystone would not cover, lost a window which was not covered.
We got lucky and our 2017 came with Sailuns so we didn't need to change tires. The toilet should have been a Tetford warranty issue. They replaced one in my first rig under warranty. Then I replaced it with a Dometic a year latter. A new piece of crap is still a piece of crap.
