There was a user with a 10.0 who had an extra aluminum bar welded right behind the bumper to double the thickness. He then added a receiver hitch where he could add a storage shelf. Looked like a great option, but I'm not sure how much weight it could hold. LL rates the rear deck at 150 lbs. max. He had a video on the mod, but looks like his YouTube account is not longer active.
If you join the Livin' Lite Tent Campers group on Facebook, there is a user named Kurt who is the current owner. I just asked him if he could provide pics of the mod, but it's in storage, so he won't be able to take pics until the spring.
