Arthur and Roswitha Waddell (plaintiffs) bought a motor home (RV) from L.V.R.V. Inc., d/b/a Wheeler’s Las Vegas RV (Wheeler’s) (defendant). The RV experienced numerous problems, including chronic engine overheating. The Waddells repeatedly took the RV to Wheeler’s for repairs. During the 18 months after the Waddells purchased the RV, the RV spent a total of seven months at Wheeler’s for repairs, not all of which were successful. The Waddells sued Wheeler’s for revocation of their acceptance of the RV. The Waddells testified that they bought the RV with the intent to use it for two to three years traveling around the country. The district court held that the nonconformities substantially impaired the RV's value to the Waddells and that the Waddells revoked their acceptance of the RV within a reasonable time. Wheeler’s appealed.
