Hydraulic jack

[marky mark]

Can someone tell me the size of jack I need for my Sprinter. I don't have a spare wheel, and therefore also no jack. I like one to have in my van. The price at the dealer was 130€ ex. On the internet there are much cheaper jacks to find, but I don't know the size of it.

So what is the min height, the liftheight and the spindelheight for the jack.

Thanks for the replay.
