Last year I was pulling into my driveway with our new-to-us TT, we had just picked it up. My in-laws were sitting in the driveway waiting to see our new TT. So, instead of being careful when making the turn I was waving and yelling to them about our new purchase.
I took the turn a "little" to tight and hit a branch sticking out.
Put a small crease into the side of the TT and broke a window.
Luckily our windows are all dark tinted, so a 1/4" thick plastic panel
painted gloss black did the trick, from the outside you can't tell its not glass. DW was, shall we say, slightly upset?
I had even trimmed back that tree before I left.
About 5 mins. after I parked the TT half the tree was gone. That's not going to happen again.
