New to Rv - questions about RV parking outside of campground

To all you folks that have stayed at a Kracker Barrel. We've just finished a 6,400 mile trip up, over and around, 20 states in 45 days. We ate at two Kracker Barrels and drove by several more. Not one of them had any capabilities of parking even one RV. You must be finding some out of the way ones. I know that I've seen on here or, elsewhere that it's ok to overnight at Kracker Barrels but, we just haven't seen any that would hold any RVs.
