How long did it take for them to crack?
Less than two years.
Over the years that I've owned my TI, I've found that using
any plastic for trailers is a bad choice in material. Even my PVC bunks crack over time and I have to replace them. Trailering is actually an extreme application for plastic because of all the constant flexing going on when on the road. Plastic can only take just so much flexing before it finally gives out and cracks. This is why trailer manufacturers use metal for the frame and wood for boat bunks, they never use plastic as a material for any structural or support members subject to stresses that cause plastic to fail.
I'm now looking for a better way to support my TI using something other than the plastic cradles or PVC pipe. Once I get the TI off the trailer for storage, I'll be removing the PVC and redesigning the bunks with something more robust. When I come up with a better design, I'll post it on this forum.
