i have a 2014 3585 in florida we use 6 months during the winter was bought in elkhart and taken to a campground in daytona so it has 1200 miles on it. we have had to the fix the dinning chairs 3\8" particle board bottoms...most of the upper cabinet hinges have had to be repaired the fasteners pull out due to the strong opening springs. the kitchen sink dropped down due to long of screws used in the mounting clips breaking the glue bond between wood and counter.have a on going leak in gray water above colorplast that i can't locate . only leaks when about full so must be on top, so i leave gate valve open ....have had lots of trouble with fridge working properly had it rebuilt twice under extended warranty, finally got rid of it and replaced with a residential samsung .the led light under awning only lasted about 10 hours before staring to fail...front bedroom ac failed and replaced under extended warranty.one plumbing leak behind udc wall.most all the drain joints leaked under the sinks.i dont use the ladder on the back except for a clothes drying rack (seems all of the heartland trailers in are park are bent down from people using them.) the caulking on the south facing side had to be relplaced after one season. we now have a leak between the front and back slide when it rains hard that is causing delamination....added a topper to bedroom slide and have checked seals that appear to be good ,but water still backs up behind it and runs down and in on bad rains... even though the bedroom slide is about 2 foot shorter than the living room slide it looks like the seal rubber isn't as big as the living room seal, might be the cause .replaced the bed ...the mattress sucks .the theater seating started to breakdown in the fist season so replaced that crap with good home theater seating. fantastic fan electronics failed and replaced under ex. warranty ... my advice is keep a close eye on everything and get a good extended warranty they are getting fed up with my claims....and try not to pull it anymore than you have to
