In my very limited experience with TC's
1. A Lance owner, with struts installed, said it was very solid
2. I don't think I'd put them onto a TC that wasn't designed to handle the strain
3. Question? What kind of tie-downs do you use? I noticed the Canadian rental companies, whose rigs end up on Alaska Highway and other rough places, use beams that cross under the chassis. No struts on the TC itself. It seems to me, just from observation, that the better-looking tie-downs, attached to box and bumper, can't secure the TC as well as frame-mounted ones. Can't prove it, just saying...
