AHA, I think you have found a valid use case. If you are towing a big (and expensive) travel trailer on a long trip, it might be worth it to install this giant thing in the bed for the trip and remove it afterward. Bed reduction wouldn’t matter much because all your stuff is in the travel trailer or hanging off the back of it anyway. I know some folks who have a separate truck that they only use to haul their AirStream, truck staying in storage the rest of the time, and this might work for them. The Patagonian explorers and deranged electrophoresis with too much money are out there, but IMHO not in sufficient quantities to justify this option.
