A 2021 Toyota Tundra TRD Pro owner reported that a tanker's rear axle struck the corner of his R-Pod 202 camper, shifting it about 3 feet to the truck's left while it remained hitched. The incident occurred about 20 miles from home after a trip to Starved Rock State Park in Illinois. The owner later said the camper was a total loss, while the truck received a clean bill of health from a frame shop.
