Thanks to you all! Good to know I'm not imagining things.
So how do you make sure you don't keep hitting things with the step? I can't really tell yet how far I am from an obstruction from looking in the mirror, maybe that'll come with practice? Also, sometimes the sun prevents me from seeing well enough. Perhaps I should just tell my wife she needs to stick her head out her window and tell me what to do! She'd love that, especially on a rainy day...
Oh, and I'll check about the key in the ignition thing. I may be always removing it out of habit. Since we only just got this rig my experience is limited.
I fell headlong down some stairs in December, and other than a lot of pain for a while, walked away, just a real pretty bruise. Figure that's my last freebie, so yeah, I don't want to break my leg in 5 places. Ain't nobody got time for that!
