Roads with gravel should be just fine, watch out though for all dirt or two-track roads. I wouldn't pull a trailer too far on these roads. Your best bet is to check the forcast just before leaving and make a decision based on the weather. In mid Nov. you could be hunting in a foot of snow (last year) or it could be in the 70's. I've seen if both ways. You shouldn't have a problem finding a camping spot, just be aware you can only pull off the road 300ft and the camping limit is 16 days. Also, you are correct, most Block Management areas don't allow camping, (you'll want to check each area), but I usually just camp nearby on some public land and drive to the area each day.
