Hello !! I could use some help/ideas on the following. We just sold our 2000 Tahoe - purchased it new 17 years ago and loved it. My wife drove this. We purchased a new 2017 LT Tahoe. She has had trouble with her legs but was able to get in and out of the 2000. Her legs have gotten a little worse and the new Tahoe seems to set higher. We have factory "running boards". Does anyone have an idea if I can add a small step or something on the boards to help her out? Any ideas at all would be appreciated - Thank You!!
