In the packing montage, someone is shown painting over the kids' heights on a wall (Ben age 8 and Carol age 15 can be seen.) At the end of the original series, they sold the house the kids grew up in, so the kids' heights at those ages wouldn't be in their current house.
The family jokes that they are really selling the house this time, unlike 1992 (insinuating they didn't sell the house at the end of the original series.) However the house is completely different.
