Many people do exactly what you do. The best ramp is at Public Beach #2 (State Park). It is up the Grand Glaize arm about a mile from party cove. There are nice ramps, plenty of parking, and rental slips available. I don't know who you spoke with, but on the weekends, the state park is very crowded. On holiday weekend, it is packed. If you want to rent a slip, reserve it ASAP. You will have no problem parking your truck and trailer, there is plenty of room. There are also some nice coves around there were you can sleep.
