Like Leah, I carry an adjustable step with folding legs in case we end up where the step is particularly high. But if their coach has air leveling as well as the Power Gear, they should be able to just use air leveling by itself to achieve their ends. As an alternative to the porta-step, I often just put out the slides and then dump air, and then hit the air auto-level. That leaves us level and the entry easy to step up to.
If they don't have HWH air leveling, I'm of no help there since we use nothing else. The electric jacks on our old coach were a pain, and hydraulic ones have their share of issues too.
