Can morbidly obese person use a travel trailer?

My short answer is a person of that size needs to buy a size appropriate unit, but even then size could be an issue. Reminds me if a story my neighbor told me. He and his wife are gospel singers and had a great big DP Motorhome/touring bus that had been built for Wynonna Judd. The very first time she set foot in it she said to sell it cause she couldn’t get her FA into the bathroom. My neighbor bought it for a fraction of the cost.
