A Rivian R1T Quad owner drove a rented 25-foot Airstreamⓘ Flying Cloud from Denver to Fort Collins and into the mountains, reaching 12,200 feet. The trip required only one DC fast-charging session, with the rest coming from campground hookups. On the toughest day, the truck used about 70% of its battery over 95 miles while climbing 4,000 feet. The owner noted that towing range is primarily affected by the trailer's frontal area, not its weight.
