My TT gets towed behind an SUV. Before the current TV, I had no backup camera, but quickly learned how to hook up by myself, admittedly with several hikes back there to check on placement. Other than that, I've always done everything by myself, including back into campsites. (My wife, bless her heart, being prone to hide behind the trailer and/or wave incoherently as I backed up.)
So if you are reasonably competent, I see no reason you couldn't handle any rig by yourself. Of course it's less work and probably more fun with someone to share the experience, but none of it really requires four hands.
