Seriously, it shouldn't be that hard with a 278 pound bike. I just measured and the hitch would be about 16" off the ground. With a 6' ramp - 72" - if I remember my geometry that's a slope of 16/72 or 22% which is somewhat steep but manageable. The handlebars will only be some 5' off the ground when it's on the ramp.
But all that is kind of moot. The plan is to get a good head of steam up, hit that baby in a wheelie and set'er down right across the front wheel chocks.....
Gunnery, gunnery, gunnery. Hit the target, all else is twaddle!
