Just doing some research

Hi All,
I'm interested in to getting back in to TT camping and touring and have some questions I hope to get some answers to. My last trailer was a Jayco pup up and I enjoyed it very much, but I slow it some years back. After 6 years I have convencied the wife that we need a trailer to bug out when the next Ike comes through. I want her to feel somewhat safe at night so that means hard sides. My questions are what wind speed can a TM safely take before it's time to just ride it out in the truck? Does TM still use wood as structural members if not what year did the stop? Thanks Dean
