[RC] Jiffy Jacks - k s swigartrackinfool said: Hmmm, my husband just read this and he said it works just fine. We have an Exiss 3h Slant with LQ and I blew a tire on it and he used the Jiffy Jack and didn't have a problem, maybe you can explain more why it doesn't work. If you will note in my original post I said that it is supposed to work on my Exiss (but since I have never had a flat in my Exiss I have never tried it to confirm). I am told (by the dealer who sold it to me) that this is because my Exiss has what is called a torsion suspension (don't ask me to explain what that is...maybe somebody else who knows more about it than me can). What it doesn't work on is my Stedham or my Logan (which are 30 and 10 years old respectively and so may have less than state of the art suspension technology). But, what they have is what (atleast in cars) is called an independent suspension, which means that the suspension for each wheel is independent of the suspension of any of the other wheels and it makes it so that each wheel moves up and down with the terrain. So, as you drive over a rock, the front wheel moves up (in the wheel well as opposed to lifting the entire trailer) and the wheel behind it stays on the ground, and then the front wheel comes down and the back wheel moves up over the rock (in the wheel well as opposed to lifting the entire trailer). Thus keeping the trailer from moving up an down every time you drive over a rock, each of the wheels absorbs the bumps in the road as it goes over them. I was told that torsion suspension on my Exiss also enables the trailer to do this while going down the road, but somehow, at the same time, when it notes that there is no pressure on the wheel (because the tire is flat???) that it automatically raises that wheel. Don't quote me on this because I didn't fully understand it when it was explained to me. I just took their word for it (although I still carry the high lift jack with me even when I take that trailer...a high lift jack is handy for all kinds of things, not just changing flat tires, the high lift jack lives in my truck). There are, without doubt, plenty of trailers that the Jiffy Jack works on (if there weren't they wouldn't sell them); however, there are also plenty of trailers that they don't work on. So, I merely wished to caution people that they either inspect their trailer's suspension (don't ask me to describe what the independent suspension on my 2 horse trailers looks like, _I_ know how to identify such a suspension, but I couldn't accurately describe it in words) or they test the jack before leaving home (and having to depend on it working in the event that they get a flat only to find that it doesn't). AND, as mentioned by Lynne, the Jiffy Jack doesn't work if you lose both tires on the same side of the trailer at the same time. Personally, I wouldn't DEPEND on one even on a trailer with a suspension for which it does work; however, this doesn't mean that I don't own one or wouldn't use it in situations where it does work. In situations where they do work, they are much quicker and easier than most other types of jack. kat Orange County, Calif. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Ridecamp is a service of Endurance Net, http://www.endurance.net.
