Is the road there good enough for our truck and 5th wheel, measuring about 50' total? Also, is there parking for such a rig?

They have a bus entrence so you should be ok

With little bit difficult you can make there but better to call them and confirm

I haven't seen any 5th wheel when I was there, but I guess it should be ok may be little tight turns in few places. I would suggest to call them directly and get an idea. They are really helpful and friendly folks
