I have a Space trekka which I love. Not so sure about the trail trekka though. When I went to one of the distributors to pick which model I wanted, I didn't really like the look of it. Mine is rear facing and thats what I was after.
Before buying I would require the dealer to explain the rescue procedure should the worst case scenario, of the trailer falling on its near side, occur. I could see no other access than the ramp and the jockey door, both on the near side.
Hopefully Equitrek have a plan for dealing with this situation.
