I've made it from San Bernardino to Wendover in 11 hours towing. It can be done.
But why not make a great trip of it? Go north thru Vegas to the 93 north. Take the scenic route on 93 towards Ely. Stop at the Cathedral Gorge and take a look. Go thru Caliente and see what it's all about. Take the Pioche town cut-off up thru town and waste a couple miles seeing the old silver-mining town, but stop in the old hotel in town and have a beer. See the old tram to the valley's smelter. Keep on going and stay at the Hotel Nevada in downtown Ely {the tallest building in Nevada (1926)} for about $50. Get a great, thrifty meal at Rocks Bar & Grill about 2 blocks east. Leave your race car and trailer on the street or at the hotel. They have an all-night security guard. I've done it with our race car or a hot rod for over 30 years and never had a problem. Get up fresh the next morning for a two-hour drive to Wendover. Get a little teary-eyed coming over the first hill when you see the salt.
Or not.
