Yes, one group of engineers blaming the other and neither solving the problem. I would buy another Winnebago (it would be my fourth) but will stay far away from the Lippert slide system.
Good luck with that

LCI is like a cancer.
So here is the deal as I understand -
Jack systems used to be HWH until sometime around 2012 - then they went to LCI. Around 2016 LCI bought PowerGear and started using the PowerGear jacks. Today - (at the GNR) I saw HWH jacks being used once again on the smaller C units, and the Grand Tour. LCI/PowerGear jacks are still used on the Horizon and I believe the Forza. The HWH jacks have 2 springs, the LCI no springs, and the LCI-PowerGear has one spring.
Slides were PowerGear underfloor slides on the big slides until around 2012. At late 2012 they went to LCI Schwintek in wall slide which have the swirly lines on the side racks attached to the side of the slide. The largest of the slides stayed PowerGear with 3 underfloor racks, but some of the remaining heavy slides went to Schwinteck and did not fair well (I have them on one side) They work fine for the smaller slide, but the heavy kitchen slide struggles. In about late 2013, LCI Schwintek came out with a heavier torgue motor which mine was upgraded to within the first year. Around 2016, LCI bought PowerGear and PowerGear had a SlimRack (thin rail) in wall slide that had vertical teeth on a rack that was detached from the slide about 1/2 inch. Winnebago went to the LCI-PowerGear SlimRack system in place of any slides that had Schwintek around 2017 and even retrofitted any warranty issues on Shwintek with the LCI-PowerGear SlimRack. Today, they seem to be moving back to the underfloor LCI-PowerGear on the heavier slides based on the new Horizon 40A having them on both sides, but not a complete transition because the Horizon 42Q and GrandTour still use the LCI-PowerGear SlimRack.
As someone stated, both LCI and Winnebago seem to accept the bad design of the Schwintek on the heavier slides, but at the same time neither accept blame. There has been no hesitation of either to upgrade to the PowerGear for original owners. Us second owners, not so much but if I end up breaking mine I would be willing to pay for the upgrade, which isn't that much in reality. So far, I've milked my kitchen Schwintek and other than It needs a little push sometimes it has worked for us. Keep it lubed, keep the voltage up when using it, and it seems to survive. The advantage to Schwintek is they are easy to maintain and repair, the PowerGear SlimRack is a bear to replace a motor.
