I was up there Mar 2016 but no trailer. I figured the biggest obstacle would be negotiating the traffic, I'm sure the key is having another truck block for you. Glad to hear you had a great trip, Happy New Year.When was the last time you've been there? I've read that the road was rerouted so your crossing the creek in 2 spots. Water was fine, not deep at all. The trailer was fine. My brother was in his truck but I didn't feel I needed a spotter at any point. I was more worried about the traffic which there was plenty considering the new yrs crowd. I'm not sure of your trailer dimensions but I wouldn't think it would be a problem if they are slightly larger than the horizon.
