Our third gearbox for the slides is about to break on our 2016 427BHs 3X. That's 3 out 5 in less than 2 years.
We went through this with 2 already. Cost us a lot of down time and trips to the dealer (an hour each way). Last time we asked if all the slide gearboxes could be changed out all at once and was told the company said "no".
So, we will just do them one at a time and the failure rate is about 2 a year. Plus as an added bonus, our Kitchen slide had to be repaired as well because the fridge was to heavy for the slide.
