Contact a local RV dealer to determine whether they sell RV furniture upgraded at the buyer's request prior to sale. Also find used RV furniture online, but be aware that shipping costs are often high due to weight.
RV dealers often provide their customers upgrades on interior features as a selling point to increase buyer interest. The replaced standard fixtures are then available for sale to other buyers at a lower cost than normal, even though the furniture has never been used. Dealers may also have furniture from customers who upgrade and trade-in older RV models. These models are often refurbished prior to resale, and the older, removed furniture is then sold.
