Two people and scaffolding is what they used to install ours...only a little more money after the cost of the awning and we negotiated with the dealer as part of the package deal and bottom line.
Aside: my contractor friend always said, learn how to do something on someone else's house before you attempt it on your own house.
Aside: lots of folks have installed their own awnings so yes, it certainly can be done.
Congrats on you new trailer.
