Maybe a dumb question

This is my first year with a TT and this morning we had some severe thunderstorms roll through. Is it safe to stay inside a TT while a lightning storm is rolling through or would it be safer to sit in the TV?

    This. I know I'm completely surrounded my metal in my TV. Since I haven't seen how my TT is assembled, I have no idea how much metal is above my head when I'm in there. Exception of course is an Airstream. I'm guessing that AL skin makes for a good Faraday cage.

    I'm thinking the TV is more structurally sound, too, from the standpoint of debris, branches, wind, hail, etc. I'd rather be in a 6500-lb tank than a 6000-lb sail made to be lightweight.
  • Not a dumb question at all. We've always stayed in the TT. If there were severe storm warnings/tornado warnings/etc most campgrounds recommend you move into the shower houses or similar sturdier building. We've never had to do that, but have always made a mental note, just in case.
  • If I were expecting lightening storms I wouldn’t camp in a meadow or under the tallest trees, both attract lightening. Other than that, I’ve been is some pretty ferocious storms and haven’t been concerned about it. I think the TV might be a shade safer, but I have no credible evidence to back that up.
  • Any metal skinned vessel can become a Faraday Cage

    An elevator, coax cable, shopping bag lined with foil---all examples of Faraday Cage.

    Now structurally.....vehicle better suited than any RV
  • I'm not an electrical engineer,and I did not sleep in a Holiday Inn last night so beware!

    I alwyas believed that a trailer framed in aluminum produced a Faraday cage.

  • I agree with the branches issue. I would be in the tow vehicle. I also try to make it a point to look at the trees when picking out a campsite.
  • Shouldn't make much difference. The vehicle should stand longer than the RV.
    Many campgrounds have safe shelters for bad storms. RV parks are basically
    trailer parks, so be careful.

  • They are both relatively safe. I would be more concerned with wind than lightning. In your TV you can drive somewhere without trees overhanging. Camper roofs aren't very strong, so I would worry about trees and branches.
