Broken copper tube on AC, thanks to Dempster Hwy

They cost an arm and a leg and can't take a bit of off-roading?

It makes me wonder..I have replaced 2 AC's on small Class C motorhome's I took on rough and rugged roads as well as one TC AC which was used the same way yet none of the travel trailers or fifth wheels that did not get the really rough stuff.

I had never really thought about it until your post but looking back it appears the same thing happened with the ones I used back in the hills also but not others that didn't get the abuse.Huh..
