I've got the little black ants. Glad to know I'm not the only one. They seem to be liking the dark areas like between hull and top cap where the rub rail is and in the side panels.
I'm going to try LYNRDSKYNRD's approach to treat around the wheels and jack as well as plant some traps maybe. I've got the same problem in my house and picked up some Ortho spray yesterday. Will let you know the longer term results.
