Well think about keeping the 5er, packed and ready during the season. Cloths, non-perishable food, and other supplies ready to go. Then if you decide to go, tote and maybe ice chest to empty the house refer of desired foods for the weekend no need for shopping trip, and GO!
We had ours in a storage yard two miles from home easy out and in. We didn't have the 7 year old, but did have two Beagles, some extra work. Our best time from me leaving work (4 miles from house) to out the gate at the storage yard was one hour and fifteen minutes, this included stopping at the house, and airing up TV tires, and installing hitch in TV, getting the tote of refer food, and dogs and their bedding.
