Little tough in the dark at early morning. It's good to have an extra set of eyes while your backing in, it's not well lit.
Small boats are a breeze, larger boats 22' and up have a tight corner to go up the hill for parking. I go out and around my truck and trailer cannot make that sharp corner.
or if you don't mind parking away from the ramp, you could use the alton public launch. the only bad part is leaving your trailer down on letter s rd. if you're by yourself, you may not want to leave your stuff unattended for that long. but if you've got a buddy with you it wouldn't be too bad. and it's free.
