If it is a dually, it will be a 1-ton. If equipped with the electrical hookups, then it may work if you are careful. Don't try it with the 3/4 truck...The other kicker is your experience in towing heavy fivers--for the cost of a 1-way truck rental, you can probably hire a company that deals in trailer moves to do it for you, and they should be insured against any problems/accidents. Just about any towing company can do it.
Just sounds to me like you ought to hire it done.
As to the awning, should be 14', but it is also a job to be done by experienced people.
