Moose river plains paddling

Hi, I'm trying to make plans for a camping trip ( the driving kind with a trailer :D ) and thought about the plains. I heard there is an area of flat water paddling and was wondering if it was near any of the campsites. I do know about Hell Diver and we recently camped at Cedar River. Also I would prefer very short carries or preferably none, actually something right at the site would be amazing. If you have a site number or area , I would be forever grateful. Yes I know this is asking for a lot but I thought I'd put it out there !
Thanks very much!
