There is, take along a Rogue Wave
(short stumpy chap with big arms) who winched the trailer under 2 tonnes of Pacific 22 after the nose was lifted with a trolley jack. Trailer was uncoupled from the car (otherwise you will damage the rear trailer rollers) as the trailer nose rose up the rear trailer cross beam allowed to move backwards on a scrap piece of wood rather than the tarmac. 10 minutes work and no further damage.
