Only 1 person answered your question, where to leave your truck and trailer while you're at the island. Well, the best security is Newport Dunes as someone said, the only downer is the loooong idle out; prox 45 minutes. If you have no problem with the long idle, the scenery is OK on the way in and out. 2nd Avenue and Long Beach are real quick, but I hate it when you come back and your wheels are gone, or the whole rig for that matter. April is usually a good water month, just a little cool until you get to Catalina...
