I have also found that Running Bear in Paulding allows winter RV hook-up. Another other option that may be available to us is Jack Pines near Munising. Their RV camping is not cleared for winter (a common theme I have found) but they may allow electric hook-up in their parking area. Waiting for a callback from them to confirm the ability to hook up. But we can use the generator if electric is not available. (I do like the convenience of plugging in for the furnace, lights, etc.) With the available options (Iron River, Paulding, and Munising area) we will see how the snow conditions compare and take the best. My trailer is set up to unload the sleds, turn on the heat, ride all day, and return to a warm, insulated trailer for drinks, dinner, and sleeping. I can comfortably sleep 3 people on cots. We have used the trailer for summer/fall camping but have not stayed in it yet for sledding. I am hoping to work out the bugs in more convenient locations first then try more remote camping using trailhead parking areas, etc. I would love to hear from any others who have done this for suggestions. It could be a great way to keep our travel plans flexible and head to areas with best conditions on relatively short notice (if I can find enough available options).
