I am a GM mechanic and wanted to chime in on my experience with our factory power folding steps that are very similar to these. If you are like many outdoorsmen and travel off the beaten path make very sure you wash your truck regularly and you will need to lube all the pivot points very regularly. We have seen quite a few come in inoperative and found that some or al the vot points are seized. The vehicles look to be either gravel travelers or just plain neglected after all the road salt after our State of Iowa road crews pour their brine or salt down. They are very cool looking but after working on them I will take my regular ol tube steps any day! Maybe this brand will be better but they sure look the same so if you do go this route I would suggest you make sure to do some preventative maintenance before you have issues.
Suzuki, Same issues with the Fords as Doug said with the Chevys, I would stay away from them unless you plan to service (clean and lube) them every other oil change. 50% of the trades we have come in have one side or the other in-op
The fw and I just bought an Expedition that have them. Passengar side was weak when we bought, I got it home and WD40’d both sides and now works great. These sound like they need to be maintained to avoid future problems.
