I don't honestly believe that anyone can project a life expectancy out of any RV. Of course the quality of our Montanas should give us a bit more longevity over the lesser rigs.
It all comes down to care and maintenance and how we use our rigs. We have Montys on here that were built in 1998 and are still going strong but I have also seen some 03 and 04 models that looked like they were about to fall apart.
You take care of it and it will take care of you and hopefully for many years to come.
