My 28F is also a 2015, bought new & have replaced so many parts I can't even count. Some under warranty but many thanks to #1 son. Have photo of both sons working in a Walmart parking lot to fix the frig door that came off in my hand. Sure did! Don't lose patience, still the best I've seen for size & price. Both sons camp next to my site when we head to the mountains in CO. Started taking them when 12 & 14... pushing 60 now. Life is good if you don't count the numbers.
