I brought my deuce and trailer in the commercial gate at Ft Lewis and after 10 minutes it left a small spot of engine oil. They had the mirrors under it and said that I had an excessive leak and that while they could deny me entrance ......they will let me in this time. If I said anything except "thank you sir", I'm sure I would have been on my way out. I'm just saying this because it all depends on the mood of the security guard on duty that day. I would be as humble as possible, if they want to they can find some reason in the manual to keep you out, but a call to the GL manager would have been my next step. Good Luck
