Garbo2018:
Managed to pull a trailer ABS socket clean out (and nearly took the airlines with it) .
If you take the airlines, rev like hell and get the unit out the way asap (you got about 20 seconds) then knock it out of gear. Not saying how I know this. 
Most common ones I see are failing to lift legs and mudguards getting ripped on curtains / internals esp on deckers. Internal straps are very strong.
