Be careful if having a welder do a homemade hi-tie and get a firm
quote. I was quoted $100 labor and materials, but my Exiss trailer has a
dropped ceiling to keep it cool. To get the hi-tie to the top of the
trailer they actually had to removed and replace the interior panels - all said
and done cost me over $300. But the guy did a wonderful job, it looks good
and it's solid.
