What I have found is about the something you have looked at it's a (MonroeŽ Gas-MagnumŽ RV shock). Here is a site that tells a little about the shock
http://www.rockauto.com/catalog/moreinfo.php?pk=118460. I have found the Monroe at Amazon. I wouldn't think traveling with a missing shock that big of a deal? If ordered shouldn't take more thing five days to reach you. Would like to know what you find out about a different shocks.
