We had a Keystone Passport towable for 5 years and decided to move up to a 5th wheel. The only issue we ever had with the Passport was the sewer smell (which the dealer could never find how it was getting in the cabin). We traded it for the 2018 Cougar Xlite 28SBS. After having it now for 10 months, we have had the entire floor replaced due to the substrate screws coming up and poking thru, Slide-out motor replaced, new inverter installed, City Water fill box replaced, cabinet door handles replaced due to breaking off in hand, cabinet hinges installed because they keep falling out and the pin box replaced. Other than that, it's a great RV!
