I'll add this:
We traveled cross country and up to Alaska with good friends. Them with their 40' DP and Toad and us with our 40' Fifth wheel and Diesel Dually. We would pull into CGs together and be done setting up about the same time. They had to un-hook their toad while we un-hooked the Truck. We both had Auto Leveling and slide outs and both had to manually hookup the same utilities. Actually when moving we could be ready quicker as it was quicker to connect the truck than it was for them to connect their toad.
Now is you don't have auto leveling on your 5er, it's an entirely different ball game.
