Let's put it this way, with the flying objects inside in a crash and the lack of any frame mounted belting in a front facing seat for anyone other than the driver and passenger these things are a rolling coffin for anyone else in the motor home going down the road. If it were legal you would be safer having your loved ones belted in your towed vehicle. I just went through this in an almost purchase of one of these death traps and decided that if I want to see the country I will do it from a nice new pickup with airbags and proper seatbelts pulling a fifth wheel. Nobody's life is more precious to me than that of my children and grandchildrens. Here's another thought, even if the couch or chair in the vehicle has belts, what are they mounted to? Yes that's right most likely the wooden floor of the slide or the frame of the slide wall, in either case these items are subject to failure in a crash. Then again think about sitting sideways in a crash, have you ever seen any vehicle testing for a crash in a vehicle while sitting sideways? For the price of these things they should be more than just a pretty thing to look at, right?
