Am going through this thread again as I have to install my haha on another Silver Streak
soon. Would have used an ordinary hitch head as it only needs to be dragged around town; TT won't be kept long, so an irritation to do a temp set-up. But may as well go through it all. Never know what tomorrow brings.
So, back to scratch with the giant 2Air thread, and then, this thread
, one of the great ones about the haha.
As the early posts had to do with tire questions, thought I'd add a pair of links
