Having a nice coat of wax helps to remove the bugs . There are other products too to coat the front but you need to remove the wax first . We carry soft towels , soap etc. if things got too bad . But having the shine helps to get that stuff off . Pat
As Pat stated, keep the bug prone zones waxed and right after a rain storm and still wet, they wipe right off and the trailer is ready for the the next swarm!
Welcome back Jack, hope to see you next year at Osoyoos. Speaking of Osoyoos, there is a car wash (not trailer) in Osoyoos that I have used several times, a dirty trailer is one thing, a dirty truck is not allowable. It is located across form the IGA store downtown.
No one's ever accused me of washing my truck too frequently but I really appreciated the free pressure wash in Tok (pronounced toke ) Alaska. Tug and tow get pretty grubby and wash places, especially free wash places, are few and far between.
