Re: [VACList] ratchet driven jockey wheel for caravans and trailers

[John Anderson <janderson@xxxxxxxx>]

I have to agree strongly with Gerald on this important point, not that 
anyone suggested manhandling their trailer around on the "rough." Years 
ago, I used devices like these in a service station business and found 
they are great on a flat <paved> surface, but could be serious trouble 
on even a moderate (i.e. barely perceptible) slope.  Most folks have 
experience pushing empty boat or utility trailers around by hand, and it 
works, but we're talking 2-4 tons of mass here, which means even slow 
movement creates a large amount of inertia. Classic car buffs speak up 
here...I think these dollies that they use for their classic cars are 
used on smooth flat paved garage and warehouse floors, not driveways.
