Unless you are a strongman contestant, I don't think you will be able to even budge it by yourself.
With a couple of strong helpers you could probably turn it to angle it in. Turning against the twin axles is tough. My Fleetwood Niagara highwall was similar weight but only a single axle and I couldn't move it by myself. The fact that my tongue wheel was missing probably didn't help, but I still don't think I could've turned it in my garage.
