Chama, NM

Needing advice on best RV park to stay at or near Chama, NM. We want to ride the train & have never stayed there. I looked at RV Park Reviews but would like to hear suggestions from some who may have stayed there. We will only be there 2 days in September as most of our vacation will be spent in Colorado. I already booked Sky Mountain RV Resort but questioning whether that is the best place due to a Rally being held at the same time. We have never stayed any where when a Rally was taking place so uncertain what to expect. Any suggestions from any of you? Has anyone stayed at Rio Chama? Thanks in advance for any help you may give.
