Hey Folks, I need some help here for my Coleman Santa Fe. We added a 3" memory foam topper to the main bunk but I'll be darned if I can close the camper down with that installed. We have to pull the topper off the mattress and place it over the dropped table then slide the bunk ends into the popup and then batten down the hatches. Even with it off, I often have to play with the screws on the hatch clips to get the top to close completely. Am I missing something here? Folks write a lot on here of using 3" (or larger) toppers on the bunk ends but mine doesn't seem to want to work out. Is there a trick to folding the canvas walls inside the camper to make this work? I've read the manual cover to cover and nothing is offered on how to fold them or store them inside during takedown. I would love to leave the topper in place between campouts and travelling so hopefully someone can help me out with this. Thanks!
