If a trailer didn't have a trailer jack, this means of transport would be pretty much useless – unless you are strong enough to lift it by hands or hitch (unhitch) a tow vehicle somehow else. Jacks can be manual and electric. With the help of an electric jack, you can hitch up substantially easier than with the manual unit, since a manual jack requires the application of physical force. Anyway, whatever the trailer jack you have, this part has to be completely workable and sufficiently reliable to prevent troubles during a journey under various conditions.

Even after I read the many bad reviews I decided to give this a try. I wasn't going to just let my tongue jack get rusty and broken. I know alot of you said it leaked and wasn't water resistant so I decided to use my waterproofing spray I use on family shoes on this cover. After a few crazy wind/rain storms it is staying dry. Hubby and I are happy with it.
