Wow, Bill, your re-thinking got me rethinking! While it's still true that the steel-cage idea is still probably the best, it's not to say that other methods are necessarily bad. There's always more than one way to skin the proverbial cat! Also, though, like you said, the RV bizz is catching up on better and stronger build methods, I'm sure partially because of the ever-increasing liability climate. It can only improve the breed.
