Some questions before I buy! What kind of door stops (back trailer door into stalls) do you like the best and why? Also steps into the LQ, what kind? Are they all pretty much unviersal? 

Also on a friends CM trailer on the back doors to keep them shut with the pin, the pin was attached with a cable. I am always losing the pins. Where could I find something like that?  You all are great!! 

You'll probably find what you're looking on these pages...

As to which door holder is the best, that's a matter of opinion..... I got some of all of them and they all have their advantages.
