After we took delivery of our new trailer I started reassembling my RV Roadside Emergency Kit. I dug out my trusty old hydraulic jack and found enough seal seeps and weeps to give me the creeps!
It was well past time for a new trailer jack.
I started searching the web and found the Powerbuilt Two Ton UniJack Hydraulic Jackstand
, by AllTrade, on Pep Boys Ebay website. What caught my eye is this unit is an integrated unit with both a 2 Ton Jack and
a Locking jackstand. That means if the jack's hydraulics failed while in use the jackstand is designed to continue to hold the load...that's a big safety plus in my opinion. It also means I no longer need to carry a separate jackstand.
After measuring the ground to frame distance on our T21QBHW, which is 14 inches, this unit looked even better as it's maximum lift range is 18 3/8 inches. That height should easily handle most tire changes. If necessary in a worst case scenario a couple leveling tiles or a piece of wood could be used to increase the maximum lift.
The unit appears to be fairly well made, the adjustable jackstand portion easily locks as the jack is raised, and the jack works fairly smoothly. At 8 5/8 inches collapsed it very easy to place under the frame even with the jackstand partially extended.
At $54.99, including shipping, I thought this was a pretty good deal.
This unit will work with my Expedition as well. I'll take a hydraulic jack over a OEM scissor jack any time....
At 18 pounds this unit is no light weight! And it is a little on the large side if you are really pressed for space.
Overall I'm quite happy with my purchase and just wanted to pass along the info in case someone else is looking for a jack. If you want or need more lifting capacity there is also a Three Ton version available.
