Flooring and bedframe can be reinforced should he enjoy the lifestyle, if he can possibly get to walkaround inside before his maiden voyage things can be shored up. I've been to dozens of RV shows and there are plenty of large men perusing TTs, maybe not 450lbs but easily 350lbs, not sure if just a 100lbs more is catastrophic unless TT is low end junk. Most steps on TTs give way to pretty much any weight placed on them, easy to just use a solid step or upgrade to quality swing out stairs. Anyway, it could be sold and put toward a quality unit if he decides to pursue RVing.
