I don't think any one of these systems are any better than the other, like snake oil salesmen would have us beleive. I don't know about the two systems you are looking at, but to change from the Morryde system to another one on our camper, it's major surgery as the brackets won't match up.
Yep, and I'm still kicking my butt for not thinking of the torsion axles when I upgraded last year. I was choked when I picked up my new axles and staring me in the eye was a big banner over the counter, advertising the torsion axles that they build on site. When I asked about pricing, I just about fell over. They would have been a few hundred $$ more than the 7k axles I bought.
When I was a kid I was going nowhere fast, now I'm an old man I'm going everywhere slow.
