I had passengers in both of my FW's and I rode in the second FW and it was as smooth if not smoother ride than the TV. Started because we had a single cab pickup and didn't want to take a second vehicle and then continued after the purchase of a four door pickup. Able to use all the features of the trailer going down the road just like a class A without the price.
In an accident would the results have been catastrophic, sure. No different than a train, plain, automobile, or motorcycle and I still use all of these to get around. Heck in this mornings paper were articles where pedestrians were killed so even walking down the street is dangerous.
