Well the 835 doesn't cover the tail lights, the camper isn't on my truck right now and I can't seem to find and example picture, but my truck's turn signals are unobstructed. I just assumed it would be safer with the "bigger" camper turn signals, but if Lance did not install them they must not be required.
In fact, now that I know what to google I can see another couple of examples of 835 owners talking about the fact that their camper only has running lights.
Well, I think that's the end of this thread. Thanks everyone for the help!
