How did you go about getting the $750? Proof of your mom living with you and her disability? She doesn't live with us yet though that will probably happen in the next few months, but she doesn't have a handicap sticker either (though she should apply). Additionally, she's only 4' 10" so that makes it harder too.Our Ram is stock height with factory 20" wheels. My wife has had a major stroke that left her right side affected and very weak. She gets in and out OK with the factory step bars. They are solid and good when wet. IMHO they can't be beat. A good fabricator may be able to extend/reinforce the mounting hardware to drop them a couple of inches.
I think Dodge still has a $750 rebate for handicap required mods? (federal law)
