Caravan Jacking
What I would really like is one of those old Jackall systems you used to get on certain cars between 1935 and the early 50's, it consisted of a lightweight pump and reservoir connected by hydraulic lines to the jacks bolted to the chassis and selectable
either both sides or just one side. The pump could either be in a locker or mounted on the A frame. I could change all four wheels round on My MG Y Type in under 5 mins with a mate
