It will depend if your toy hauler has a beaver tail and how long it is. Longer trailers will typically sit higher which will make the break over angle sharper. My 700 lb Concours was never an issue loading or unloading. I would pop the front wheel on the ramp and get a little momentum to get the rear over the ramp lip. I have long legs and learned on dirt motorcycles, so this may not be a simple if you have trouble reaching the ground and have not ridden off-road. Unloading, I leave the engine off and in gear. I have my right foot on the rear brake and my left hand is is holding the clutch in. I do not use the clutch to slow me, but I know I can release it if something went wrong with my foot brake while backing.
As others have posted, raising the hitch or pin will make it easier to clear both angles on the ramp. If that is not enough, you can use jack stands under your ramp door and use additional ramps/boards to get to the elevated rear door.
