Is this the first of many more float trips or just a one off situation ?
Do you really need to buy a float of your own, or could you fill the requirement by
hiring or borrowing a float to do the job, or could you ask for the assistance of a friend
with the right equipment and expertise to assist you?
Is you vehicle suitable and safe for towing, without risking breaking the law, damaging
your car and perhaps jeopardising your vehicles warranty and most importantly
without risking the safety of the people and horses involved.
Are the combined weight of your horse and your float within the legal towing capacity
of the vehicle. That is, the manufacturers recommended towing capacity.
