Yes, we keep two small step stools in the hangar, and a folding portable one in the cargo compartment
The Cardinal is pretty much a cult airplane; in the mid-1970's Cessna hoped it would replace the Skyhawk, but the beancounters bought a warehouse full of 150hp engines before the design was flown, to only discover that it really needed a 180 hp engine. The A-model was severely underpowered, and had a nasty tendency towards stabilator stalls in the landing flare. The -B has a 180 hp engine, a controllable-speed prop, and a slotted stabilator; this solved the major design flaws but the reputation of the type was damaged.
The struts were eliminated by using the same airfoil as the strutless Centurion wing in a cantilever design, but unfortunately this did not deliver the same performance when scaled down to a 4-place airplane...hence the need for more power than the original design called for.
It really is a lovely airplane; the raked windshield and forward-placed pilot's seats provide excellent visibility (although a more forward center of gravity than one might like), and the wider body and doors than a Skyhawk are serious comfort items.
