I think you will be fine you just have to manage it through the camper door which will be a 2 person job. I almost got my 10'8 through the door of a caravan it just didn't quite have the width to the back wall due to the shower.
of course I don't have that problem now I have a Vito it's longer than an iload, I can fit a 12'6

Suggest maybe some of that sticky Matt stuff on the floor to stop it slipping too much and in a board bag
