enclosed 2019 cargo trailer 7x16. Days after i got it my Honda 6,000 KW generator exploded inside the trailer.  To my  surprise the inside chip board and outside top and sides both burned.   I have replaced the outside with 29 gage steel pre painted.  and inside i used foam board insulation and plastic sheeting.   I rewired and replaced lights and checked brakes.     7,000# GVW.   two axles with brakes.  Sheet metal is rough but it will work  with a little TLC.  I will try to answer any Questions  I had a heart  attack while repairing this and it needs finish work and I don't need it now.
