Thanks for all the info.
Kind of spooked thinking about pulling an aluminum trailer off road very much.
The dealer says you can't hurt them but I don't know, it would really suck to end up with a $19k twisted piece of chit. But at the same time there are still a bunch of old pots going down the road so hell if I know.
I think we will just stick with a steel. Heavier but stronger not to mention $6k less money.
