Was looking on GOOGLE for a side TC mounting. I saw one going down the road the other day with two KAYAKs mounted to curb side of the camper...
Did find this photo of mounting two kayaks in the vertical position on the back of the Camper... This could work for the TC as well...

I always wanted to go with the 4WD truck camper but with all the stuff I carry I know I would have to use a util trailer behind it.
I can carry some serious supplies on my off-road trips using my front deck and my truck bed. No way could I survive without all of the stuff haha...
