Sell truck and camper together or separately?

I have found, over and over when selling some big item, it just takes one serious buyer, either way you go. The market will take care of the price, no matter how good you think your stuff is. I think there is a cadre of folks out there who would appreciate a combo with the bugs worked out if they do not currently own a truck or camper and are starting with a clean slate. I would start there first. And, I keep hearing the phrase, "Are you feeling lucky?" when it comes to trusting the leaky 6.0L Navistar engine. I read that it was the first Warranty group ever to surpass the $1B mark. Ford pointed the finger at Navistar and Navistar pointed the finger at Ford.
I just sold my classic 1982 CJ8 Scrambler rock crawler for $12K, delivered. Whoda thunk? It just took one buyer.
