backing camper into garage with a driveway incline...help!

We can back it in with the truck, but the trailer is coming in at an angle because the driveway has a incline and it's not clearing the garage. If it were coming in level it'd be fine. So I'm hoping there's a way to get it level before entering the garage..?? Idk...maybe have to build a ramp to level the driveway? Not sure how to go about that either :/ A little in over my head here.
