We have a 30' Keystone Sprinter. We purchased it just over a year ago and have spent a number of months in it already. To date, the only problem we have had is draining the black water tank. (Five females produces lots of TP.) Our dealer gave us a remedy, however, there is no known cure. We have been told that there isn't a black water tank made that doesn't have to fight gravity, and therefore causes some problems. All in all, we love our Keystone, but no more than our Coachman 27' trailer. (Except for size/space.) If you can, visit a RV Show. Chicago just had their big one for the year. Nice way to see all the options. Hope this helps!
