WOW, very bad! We don't know the story about what happend... hot shotter following too close to 18 wheeler that emergency stopped, came up from behind too fast, 18 wheeler passed, cut in front, and braked, hot shotter brakes inadequate brakes etc... There's no doubt this guy was heavy.
My experience towing heavy RV from several years and towing heavy generators last hurricane season my biggest comlaint was 18 wheelers passing me an cutting over 15-20 feet in front of me, effectively eliminating my safe following distance. I like several hundred feet following distance when running loaded at 65MPH. I anticipate heading out on first camping trip with new Super C MH and towed (toad) Wrangler... we'll see how this experience is the same and different.
Hope the driver was safe and Cheers to all, Ron
