Marge takes the kids on a Sunday drive while Homer is at home attempting to clean out the garage. After Homer suffers a garage-door-to-the-throat incident, Marge wants them to buy life insurance. Homer however is deemed uninsurable. Fearing that with no insurance for Homer they will go broke, Marge starts cost-cutting measures. Homer is against these new measures and takes the nest egg that Marge has made and spends it on the down payment for a new motor home. Marge tells him to enjoy being the king of his new castle, because she is no longer speaking to him. Homer is now living in the RV in the backyard and he and Marge try to entice Bart and Lisa to come and stay with them. Homer then opens up the backyard as a RV park, until Marge puts an end to it and they get into a big fight, which makes Bart and Lisa take action. Bart decides they need to take the RV back to the dealer. Homer and Marge try to stop the pair who has managed to get the RV onto the freeway. The RV crashes onto a Turkish container ship, which is leaving port. With the right enticement, mushroom soup, Marge gets the ship to turn around, saving the children and what is left of the RV. The RVs fate is determined when Homer try to put it on the dock.
