Glendale car and trailer parking

[chachee52]

I have a friend that is going to let me use his fishing boat a few times this year. I am a Gilford resident, but will be using his truck to tow the boat. Looking at the website, I can get a guest pass, but that only allows the car to park, not the trailer. Is this true? If so, how do others get around this? Seems silly for me to bring the boat down, take another 30-45 min to go back and forth to my house just to get my car to park there, then do the same at the end of the day all because the guest pass can't park a trailer.
I plan to go down to town hall and ask too, but figured someone on here might know before I get a chance to go down and ask.
Thanks in advance.
