Congratulations and welcome to the group!
You should do just fine. I travel alone with my dog 100% of the time. The worst part is lining up the tow vehicle and trailer. This gets easier with time/practice. Some purchase a camera (but not me).
Most everything else doesn't require super-human strength, or a genius IQ (thank goodness). Level your trailer, side to side, with leveling blocks before unhitching - just back up onto them and then "chock" the wheels. Level front/back using the tongue jack when you unhitch. The stabilizers are not difficult, just a lot of turning the crank. There is an attachment for cordless drills that can be used, if desired.
So, can you do it alone....YES! If you have any particular questions, just ask!
