Gypsy, I've seen the EZ Connect but it looks like it only works when you are pulling the trailer and not much for pushing. They stated on their website not use it on a grade. The TRAX EZ-Secure Loc looks like it will work much better and its much more compact and way cheaper too.
check it...
Marco, that had to be a bit scary. I wonder if you had any weights to place on the back of the ranger to see if it would become more stable? I'd hate to see you loose your load going up a grade and have it tip over and cause bodily, trailer and ranger damage. :smileo
We have a TRAX Power Dolly. It's surprisingly quick, quiet and powerful. Better yet it's very easy to connect to my trailer and extremely stable under the trailer's latch assembly too.
