Build a Tow Dolly?

["John Harvey" <50scars@xxxxxxxxxxxx>]

I have used tow dollies.  They work quite well on small light narrow
vehicles, but wide ones will end up getting dents in the doors or front
fenders from turning corners.  You really have to watch where you go with a
tow dollie, because you are not supposed to back them up.  Installing a car
on a tow dollie isn't much less work than putting one on a proper trailer.
There are no additional brakes with a tow dollie to help with the extra
load.  If your tow vehicle  isn't at least as heavy as your towed one, it
will keep you very busy, expecially if there is wind or tracks in the road.
You essentially have a wagon, not a trailer, and it wants to jerk and
wander, unlike a tandem axel trailer with the axels near  each other.  I
don't know if your car has the pump in the rear of the transmission, but if
it does not, you will need to disconnect the drive shaft before you tow, or
else put the car on backwards and tie the steering wheel straight, or you
will burn up the transmission in short order.
     If you still insist on a tow dollie, buy a commercial one.  There is
more to one that works than meets the eye.  Of course if you look around,
you can buy a proper used trailer for about the same money, and trailers are
really useful for other things than just hauling the car.
