Is there truck parking in walking distance.

All parking is on the street. But if it's tractor trailer, you can find parking and just walk a little ways.

There is parking lot in front and on the sides with many handicap spots.

There is plenty of Parking for cars and pickups around the Museum and the House. And still more within walking distance in the small and delightful town of Winterset. However, tractor trailer or heavy truck parking may be a bit more challenging but still attainable. You may have to walk a little further but as I remember it there are areas north of the museum that are large enough.

There is a small lot to the north of the house on the east side of the museum

On the street.
