Life could be easier if you took out those rocks at the bottom right and widened the approach by flattening the hill at the bottom. You could also have the driveway reworked so that there is less of a valley at the bottom. My driveway is also on a hill - not as long, but I have to do the scoop and then go around the corner on the left of the house where there is 80 feet of pad. Only thing I remove is the anti sway friction slider. My skid pads scrape when pulling out.
What I really think is that your just fishing for compliments! :P You seem to have it down. I'd say a few driveway improvements would be all that is needed to get your dream TT in there.
