We have "full-timed" in our 2013 27WP for 16 months. With the exception of a missing tail light lens which fell off on way home from dealer (Forest River shipped me replacement assembly & I installed), and a failed check valve in fresh water pump (fixed by FR dealer in Hot Springs, AR), we have been trouble free. We found our dealer (The Outpost RV) in Middlebury, IN to be very helpful in each situation and in answering questions on minor issues.
As a result of overall quality for the price, and excellent manufacturer response to 2 warranty issues, we are restricting our current fifth wheel search to FR products only.
As far as towing, we have towed from the east coast to Texas on the south, Dakotas & Montana to the north and on to Oregon coast with zero problems except for a failed brake controller on TV. We tow with a 1994 Chevy dually 454ci, using an Andersen "no sway" equalizer hitch which has worked flawlessly for over 5000 miles.
Thanks FR for a great product at a competitive price.
