TC and Tonneau Cover?

Thanks-it helps to know it's possible. We're in the "what do we have to give up" stage of deciding if a TC is the way to go. We've figured out the boats, bikes, and excess gear (we have a good trailer), the dogs will have to ride in the cab because of no cap on the truck (guess we'll have to deal with wet dog smell!), and our son will have to suck it up and sleep on the dinette bed or sofa bed or get a tent. Still will be at least a year before we make a decision but that helps a lot. At least we can cover gear in the bed of the truck when the camper isn't on.
